Interesting play! I like the aesthetic you went for, and the musics are nice (I also appreciated the fact it's possible to switch tracks!). The dialogs were very funny sometimes, which I enjoyed too.
I'm not very good at platformers so I couldn't finish the game (yet) Also, maybe I didn't see it but I think it would be useful to allow players to check the controls again with the pause menu, because I couldn't find how to do that so I had to go back to the main menu... The last drawback I can see concerns the font, that I find a bit hard to read if the game isn't full screen.
But overall it was fun to play and has a nice feeling to it!
