Shwoop was super fun to play through! The quantity of unique mechanics and level layouts was absolutely staggering, and the game felt like it steadily increased the difficulty as it went along. (Funnily, I didn't realize that you could rotate the shooters until I was on Level 19.) lol
I occasionally encountered a glitch where a line I drew didn't have any collision, so I had to redraw it. It wasn't a game-breaker or anything; I just thought I'd mention it. Overall, fantastic job all around!
