The mod works but sometimes I step on the button and the wave doesn't start, forcing me to restart the run.
I've done everything in my power, but the mod isn't working. Just putting me in normal Greedier. Yes I'm in Afterbirth+ and yes I've verified files integirty, multiple times actually.
dude i have afterbirth+ did all the steps and everything, it doesent works Help?
whenever I enter the arena it crashes my game
It doesn't work for me when i play arena mode its just greed with the different walls
It would be cool if there were different levels that would produce a victory trophy. First attempt and I just finished wave 101 on hardmode. I still have full health but have just lost interest in the run. Restarted to try new run.
Hey Dude Bro, It Just Changes The Walls, I Tried Greedier Mode And It's The Same, Piz Help ;-;


i downloaded it and anything but when i picked all items and jump to the boss room it disappears
what disappears? are you playing mac or linux cause those are not tested
Why this mod doesn't working? I did all things from instruction, but it still not working! (I probably made mistakes, because I don't know english language. Don't judge me )
go to The binding of isaac on steam and "Verify Intergrity of Game Files" in properties, this will download the latest version of Afterbirth+
it seems like your steam profile isn't setup yet
Try to get past Wave 20 they Say
Wow, you must have had really good items
ipecac + Pyromaniac + Quadshot +20/20 Good
Помогите , как поставить?
good mod, but which version is rebirth compatible? thanks!
there is no version for rebirth, only afterbirth+ because this is made with Lua
The constant updates are showing you take good care of requests and suggestions. You are the pretty good
Really Cool Mod would love to see more at some point
Could you add a few trinkets for the player to chose from in the starting area? This would also give a reason to include trinket space giving items in the itempool. Speaking of which, have you noticed that the same sets of 5 items repeat themselves? I mean, if you encounter a set of items A, B, C, D, E, the same set can be seen even in new runs.
About that trinkets, yeah that is a good idea. about the 5 items repeating is the fault of the lua api for not having a good random system
Hello this mod has some charisma!, but how about doing an arena that ends with the death of the poor isaac? let me explain, it is possible to remove the limit of twenty waves and increase the difficulty wave by wave? i don't have any programming skills but i think that this is possible with increase the red heart damages(for example, half red heart in the first floor, one in the second, two after the 9th wave an so on), and insert the countdown clock with the spikes on the botton
I'm really appreciating your mod!
I can make a choice for the player on the end, or win the game or go endless. a timer is also possible, thanks for the suggestion
Thank you for the rapid answer, and what do you think about the increase of the red heart damages, i think that is the most valuable variable for become this mod letterally addictive because, you know, when you gain a lot of passive item isaac could become a war machine
That would be a good idea, also giving the bosses more health as waves progress can make it more difficult
I noticed that after winning the arena if you start a normal run the text saying you won is still there.
Fun mod but was really buggy for me. Of my 5 runs tried so far I won once, died once, ended up teleporting out of the room to ultra greed when I used my spacebar item (unicorn stump.. not sure how that happened), and 2 times the button on the ground used to start waves did not ever spawn...

Worth playing forsure tho!
Good idea, dude! I do like this mod a lot!

These are some bugs i've seen.
1) You can switch spacebar items in item pools without losing other items
2) With Apollion voiding all items the game crashes
3) If you fly, you can take an item, go off the bridge and the items don't disappear
4) If you take items like usualand exit, when you continue you restart from the first 5.
5) The button is still pressed when i clear a wave but if you walk on it, a new wave begins at usual.
6) defeating the hush will result sometims in a rain of spawning collectibles, and none trophy
7) if you exit without clearing a wave, continue the game sometimes results in clearing it free

These are some ideas:
1) Instead of the bridge, make ten item rooms (for the exit and fly bugs)
2) every 5 waves, make an exit with a shop or item pools, like this you can reset holy mantle (too underpowered) and pinking shears or lilith active (too powerful)
3) the charcater starts with no charges, for apollyon
Thanks for your advice, i will work on the bugs and thank you for the good ideas, i don't think i will use more rooms for the itemroom but i will remove the bridge and give it more features
Other things:
1) Only the first time apollion had the void, now, satanic bible? Probably another bug...
2) Teleport items means go for rooms like the greed mode shop, but without exit (probably the best thing is remove them from the pool)
3) After the first 8 pools, an angel and a devil room would probably be a good idea
1) that is not a bug, the void is a bugged item, that's why i gave him an other item
2) i have removed teleport items from the pool, only sometimes they could come (idk why that is)
3) i think with pools you mean waves, yeah because those waves are easy
For some reason I can only download the most recent version of the mod. Anyone know a fix?
You can't download an older version, also older versions have way more bugs so i don't know why you would want an older version, probably because it was easy to cheat
Very fun mod but sometimes you can pick more than one item
cant you just get flight and take all/most of the items?
in the newest versions of this mod not anymore, items will go away when not picked
I would appreciate a Afterbirth or Rebirth Compatiblity.
Only Afterbirth+ has support for Lua, Afterbirth and Rebirth are not posible
Very fun and simple mod, it's basically perfect for when you want to play some Isaac but don't feel like doing a complete run.
I found a bug if you go appollyon and eat the items the game freezes :P
