Very cool idea with having to play the same level repeatedly on multiple dimensions! I couldn't beat 1D, had difficulty wrapping my head around the jump timing and couldn't figure out how to get past the lasers. Story was fun and I loved the art. I noticed some clipping and Z-fighting in 3D where the platforms overlapped and 2D could maybe use a background, but then again 3D didn't have one and it didn't bother me. Music was good too. Controls were maybe a little imprecise, but I got used to them. Altogether, very nice job!
