Funny idea with those two dimensions. Gameplay is challenging and might be even more funny with some polish. Sometimes it's unclear in which dimension are the platforms. Also the controls are unecessarly confusing, when I was trying to use 'space' I keep mixing up the jump with dimension switch. Better to stick with the standard approach, it's just makes user experience less frustrating. Anyway, it's really interesting game and has a really good level design. Nicely done!
