I found your game art and story very enticing !
however there is a lot of technical issues...
-Mainly with the hitbox which is really important in a platformer game. For instance the change of hitbox between idle and walk animation is disturbing for the player, and overall it is difficult to understand how far the player is from a plateform or a trap.
-I didn't find a way to fight back the ennemies and boss.
-I also got stuck at the bottom of the level because crumbly plateforms were not reapearing and falling off the map didn't kill me. With no reset button I had to close and reopen the game.
Nonetheless those are all technical issues and the game ideas/lore remain really interesting.
