Yep you basically listed every main bug in the game. I didn't notice enemies walking through walls very often so I didn't fix it (plus i noticed after i submitted) and yeah the 'merge' thing was a bug but as I wrote in one of the levels, I said its a feature becuse I didn't know how to fix it lol. And that bit where the enemy killed you on the goal was intentional, but I shouldn't have played the win sound or animation. Anyway, thanks for the comment!
