Nice level design! I'm not that good at precision platforming, but I got through the levels (at least a 100 deaths per level hehe). I like how the second level introduces a new mechanic and keeps building upon it. The music choice was on point.
The room of the second screenshot (tight yellow room with the red moving squares) was the only one I felt was a tad too unforgiving, but definitely doable.
I have never played VVVVVV before, but the whole mechanic is easy to understand, so it's the kind of game you can just pick and play. And before I forget, thanks for the generous amount of checkpoints! Def saved me.
Great job!
