I like the black/white minimalist design, as well as the retro style sound effects.  Not really being able to change directions in mid-air made jumping around a bit difficult, and I ultimately got stuck on a level where I couldn't switch realities and I couldn't find a way out. I think your concept has a lot of potential for interesting levels, it's just a little bit on the difficult side right now.  Overall, though, I definitely had fun.  

If you have time I would really appreciate if you could rate my game as well, although I understand if aren't able.

your game features in my video 

Nice game, very unique idea I like how when u shift the dimensions u can jump higher, Rated it! If possible do rate and play my game :)

Very cool concept, and I love the black and white contrast design. Well done!

Interesting game, its very minimalistic and simple! I like the fact you need to switch (or in your games case, flip) between the two worlds in order to progress through some levels.

Really cool main mechanic! The movement is a bit slow and sluggish but the art is pretty charming. I'd love if you tried my game as well (:

i really like the minimalistic style and concept. Very nice

Nice game! Looks like we had the same idea :D
