Thanks for the review! I'l try to clarify some points:
1 - Probably you started night right over an enemy. I will make so that they are partially visible and you get spawn immunity later.
2 - My game was supposed to be difficult because moving and attacking was difficult, not because of the enemies or the shards, which would be relatively easy on a normal side-scroller. It was intentional.
3 - Like, when you roll over an enemy, you don't get the damage feedback because it's just a tiny 5 damage, so I thought it wouldn't be necessary.
4 - Tgis may be because of the calculations to do this. In a very specific frame, you might roll a bit faster or slower, and, depending on which frame you hit the enemy, this could happen.
