Great game! I had a lot of fun and even ended up playing it a second time. However, I have to admit, I won but I’m still not entirely sure why, even though I read the introduction :)
The snapping to the stars is a good mechanic, but it gets a bit difficult if you have to cross 5 stars that you don't want to target. A solution I can think of: as long as you hold down the A/S keys, snapping is disabled. After releasing A/S, it triggers the snapping function.
The music fits beautifully and it's a very polished overall experience! Great job!
