The amounts of levels you made in just 9 days is impressive! The difficulty curve felt just right.
I liked how the lights would pulse. But placing them felt like a chore. Maybe if RMB only removed the last light, it would help that? I liked the flying mechanic, but when it was introduced, I had some trouble figuring it out because I thought the flying pickup was a mouse icon telling me to click. Crisp pixel art!
All in all, a very fun game! Thanks for sharing!
