Hey, I saw your game on twitter! Your pixel artwork is quite good, great job there :) I see you got some good feedback from other people already, so I have not much else to say haha still, I agree with Slecornu in that this game could become a really interesting metroidvania, and getting an upgrade for carrying more stuff would be a nice addition there.
Also, the ending was quite unexpected and I have mixed feelings about it hahahaha again, great job!
