I tried to make a micro deckbuilder for this jam - I feel like you did the same but for a platformer. Fantastic game you made here. Perfect mix of speedrunner and platformer (two of my favourite genres). Addicting game loop and great level design makes for a lot of replayability.
The presentation is also a simple and effective, and I love how the colour slowly changes as you progress. So much polish and nice details everywhere. Great job making this.
