Pretty good game, I like the puzzle element where you control and utilise the dead versions of yourself to progress.
I found the movement physics to be floaty though and the acceleration when moving left and right feels too strong.
The physics on the minions also makes it awkward when trying to use them as platforms and resulted in some cheap deaths with the spikes.
I also found the audio to be grating to a degree, namely the music and lasers. The music volume could be turned down a tad but it's fine other than that.
This is a good first game effort!
