Thank you for playing! Actually, the first two "bugs" are intentional. You stepped on illusionist platforms that will dissappear when stepped on, but still allow you to stand on them, maybe i should've made that more clear. The enemies when killed, will rise to infinity, to portray ascension. I worked on trying to fix the third bug, but I couldn't figure out how.
Instead o settings `visible = false`, you can animate `modulate.a` from 1.0 to 0.0 in like 0.5 second. Then platform would disappear gradually and it would be obvious that it is intentional.
And I think the enemies that flew away were not killed, I was running past them and all 3 just flew into the air.
