I'm so impressed that you completed this in 3 days (on top of the limitation from the Mini Jam)!! The level design is great, the music is great, and the assets are really well-implemented.
I would love to see this expanded, and if you're planning to I would say:
1. Not sure how you would do this, but potentially hide the answer to the puzzle a little more for some of the levels. For a few of the middle ones I would just move my cursor a bit and the angle would be obvious because it was the most connected thing on screen
2. Small and medium ships look pretty similar, I might find a way to differentiate them
I really hope you expand this because this would be a really fun little game to play with some more features.
