The art and character designs are really really nice. I love them.
unfortunately i had the bug where i couldn't pass the room with the penguin and the getting caught did nothing. I restarted the game a few times but it was the same each time. If you are a potential player reading this comment then do not let the bug put you off trying it, it's 100% worth your time to try this game out even if you do encounter the bug.
I see the potential and what you were going for. I think the gameplay idea is very unique and has potential for a lot of fun level ideas.
My only critique which isn't bug related is that i don't think it's very clear to the player that the sneeze knockback can break you through glass at first. I see how you tried to teach the player by forcing them to get through a glass door in the first room to progress, but it's very easy to miss the fact that you smashed through that first door as you are probably focusing on figuring out how to pick up the first vase.
Overall, it's a very nice game with a lot of potential, and i absolutely love the protagonist's design and walk animation.
Good job!
