Really enjoyed this one, nice work David :)
Narrative was compelling, loved the colours and animating background effects. Choice of music and sounds paired up well with the game. Controls felt good and responsive, although it did take me a surprising amount of coordination to use the mouse and keyboard effectively haha.
My only critique would be that I did find the chase after learning to wall jump a bit too unforgiving and got stuck there a few times, would have been happy to respawn at the last door/checkpoint.
For a one man game jam effort, great job!
