B1 - Thanks really. I did a colossal bug and didn't tested it, sorry for that. When I optimising code I just forgot to toggle some pins. Even achievements were not given out. Right after I read this I started to fixing it and it works now.
B2 - Kevvy-D reported to me this bug before. It strangely appears when custom difficult picked at number of waves 1. You had same number? I played few rounds right now at difficulty and tried similar what Wolf said and nothing. Really strange bug. Seems I need to work on fence climbing part
B3 - HMMMMM. If enemy downed. It means they in knocked out state and if they in knocked out state they can't technicaly attack (its hardcoded in other states). So really strange
B4 - B1 - fixed
B5 - Yeah, appeared this too :D. So I don’t think we can fix this yet, so that there is less desire to spawnkill. Or just make enemy invulnerable during climbing.
I need more search for B2. Thank you a lot for bughunting!
Something I can reveal to you about next update - I'll try to make new enemy - kobolds
