In my metroidvania game in NESmaker 4.5.6 my player is sometimes hurt for no apparent reason. It's almost like there are invisible hurt tiles. The problem is that it doesn't happen in the same place every time. Can it be related to the hurt_monster script? I haven't done any tweaking to that script that would explain this behaviour. Has anyone else experienced this?
Here is my hurtPlayer_MetroidVania.asm:
