Cool adventure, interesting narrative/ending aswell. Gameplay wise I liked it, even tho is a bit hard to predict where the enemies will be the knockback makes it very funny.
The boss battle took me a couple tries but eventually got it, for some reason my blaster wasnt shooting, I remember picking up 2 of them in the previous room so there should be enough ammo.
Overall is a fun game to play, I also like the variety you added using the boulders and spikes breaks the monotomy of only killing enemies. Congrats!
