I like the graphics quite a lot. It's simple and easy to tell what kills you and what doesn't. It's also really cool to have a cutscene stage, though I'm not too sure what is happening there. There is an impressive number of levels. Some of the levels can get frustrating to clear, but the difficulty curve is well done. The levels are also way less repetitive than I'll expect.
One thing I'm curious about is the reason for having an additional input to dash, rather than making the player dash on contact. It feels a little strange to have a specific key dedicated to something that is not accessible most of the time.
I would also suggest zipping the .exe and .pck files into a zip file and upload that instead for convenience.
Regardless, great submission!
