Hi! I made an account on itch.io just to review this game. I have to say this is a lot of fun! I do think some things can be ironed out.
-Sometimes using your left-click blink ability on those slightly sloped bridges can glitch you into the bridge and I believe there isn't a way out. You just have to restart the level.
-There were also times I felt some paths you could take to the goal seemed too difficult and long to attempt. I.E. the lower path on the BOSS level.
-Maybe different music for when you summon the boss?
-Maybe when your character dies his hands should fall down off screen rather than just move like he's running?
I enjoyed it nonetheless and believe the boss was pretty great. Don't really understand why people said the boss was challenging or didn't know what to do. It did take me a few tries but obviously you're just running back to the beginning. Lol. I guess people need tutorials left and right. Great game! Reminds me a lot of A Story About My Uncle
