I think its personally because i'm a bit bad, but i just had a run where in the first boss fight plum spawns and even with two B.bobby i don't have time to stop him and i waste a charger.
I suggest that at the start of a boss fight the enemies that are spawned are  a bit after the boss  gets up.
Also the charger replacement is a bit expensive so it makes it really frustrating to lose one and sacrifice discovering new items and "deck building".

after leaving the game alt tabbed for a while, all sounds stopped playing until i closed and reopened the game

It really needs a 5th baby slot, it would probably make the game harder because you'd want to experiment and maybe use a weaker tower. I've only used like 6 babies so far because I don't trust anything else enough to give it one of the three slots I have free after my economy unit. I just "completed" my first run, I can't imagine picking anyone besides crisper, freezer, or ghost as my damage unit. 

Also, game crashed on boss three.

During boss 3 , I was just about to kill so I'm not sure if it was on the kill or bad timing. I had also literally just used red candle killing one of those wraiths who shoot freezing tears who was over the gap.

The game get's detected as a virus and my pc automatically deletes it, any chances of that being fixed?

i get this error message when i try to run the game

how do i make this disappear :´( 

So,i played some time and noticed some bugs:
1-When you die and you go back to title screen.stage where you been dont erase.You can replay level there you died.

2-If you continue(when you died) and restart you babies will stay.I obtained 2 baby stevens

I like that game.Wanna see more in future!And thanks for Russian language!

i have to say, i was ready for this game to come out but was also ready for it to not run on my computer cause my pc is trash for running games but this game was  awesome and it runs perfectly and i would really like to work on it more and fix thing/do more work on it cause this is the best isaac fangame (and first one) that i have ever played

also the only bug that i ran into was when i unlocked snowball and used it the next time i played it said that it will freeze anything by a 3x3 lane but when i wanted to freeze to enemy that are at the same speed but in 2 different lanes it doesnt freeze the down lane of this 3x3 radius so its literally just infront of the plant 

but yeah this game is awesome other than some bugs and thank you for giving us this masterpiece 

You can replay Isaac getting dropkicked when you die by right clicking, at least in my instance. Do not remove this.

So, the game crashed with an error.

FATAL ERROR in Vertex Shader compilation

ShaderName: shBlackNWhite

memory:67:22: error: syntax error, unexpected NEW_IDENTIFIER

at gml_Object_o_card_Draw_0

Triggered after starting a new run and "Ready, Set, CRY!" Tried to use an emulator to play this, but the game worked alright with the menu and getting in the game, so I don't think it's that.

I got an idea about synergy of  passive item "Flip" and Lil Loki. Using Flip on him will rotate only 45 degrees, so Lil Loki fire diagonally, like Lil Wiz. And one more, do u speak russian?

not sure if it's a bug but after defeating ark 1 the game goes on forever. It doesnt give the trophy. Doesn't even spawn enemies

Mongo Baby doesn't shoot on adjacent lanes when in front of Little Steven

Last Patch: Blue cultist goes offscreen when horded by friendly monsters (Mystery Egg) making me have to remove them for the cultist to appear to kill.

Sometimes the grid fucks up and starts placing babies off-tiles (notably on minecart levels)
