This is a nice platformer with lots of potential. The clone mechanic is very interesting and really keeps yourself on your toes. The only downside was that in levels that were already very difficult it became a bit frustrating. The combination of a lot of movement momentum and large hitboxes on the spikes caused a lot of deaths that felt unfair. I got stuck on the interior level that has spikes on some of the platforms; I must have tried it 20 times, and I got to the vertical climbing section at the end 3 times, but all 3 times I missed a jump due to momentum and my clone ran into me. It was fun getting to that point though. Excellent pixel art and audio. Great work!
