I thoroughly enjoyed this one! The effort put into the customization is nice, even though I mostly went with the ship that was a bit reminiscent of an A-Wing, in pink. The music was very fun, it somehow feels nostalgic.
I'm also thankful that you put infinite continues - or at least enough for me to finish the game, if they're not infinite. I played kind of badly and my score was really low as a result, but I got to see everything you made!
My only two minor gripes would be the controls indeed being a bit "slippery", like RedWool also mentioned, and the fact that something about the pixelation, or interplay between the resolution and textures and models, kind of made the whole screen flicker a bit during gameplay, at least on my end.
Overall, I had a great time with this game, well done!
