Ayy, got a 600. I don't know whether that's good or not, but it felt like a pretty good score to me!
Anyways, I thought it was great game! I like how you chose to challenge yourself by making a simple game in as short a time frame as you could with specific goals in mind. My "simple" game goals usually end in failure, haha. But yeah, I'd say you deserve a pat on the back! The feedback given whenever you time things perfectly was indeed pretty satisfying, and the graphics were really nice as well! I will admit that it was challenging enough that I didn't exactly feel "relaxed" while playing, but that still wasn't all that much of a problem. The game was fun despite being so simple. Well done!
