Really nice pace on this one.
The bit I actually want to flag is the volume slider in game. Sounds like a small thing to praise but it really isn’t, I’ve played a stack of jam entries this week and nearly all of them have me reaching for my speakers instead, and I noticed straight away that you’d bothered. I’m putting one in mine because of yours, honestly.
Same goes for being able to just start. No menu to work through, no setup, I was playing within a few seconds of the page loading. On a game this fast that matters more than it would anywhere else.
You mentioned on the page that this wasn’t the first thing you tried, what were the ones that didn’t make it? :)
