I've played a handful of both games where you work with past loop versions of yourself, and games where you have to draw a loop around enemies to defeat them, but I think this is the first jam game I've played with both, and it works unexpectedly well here! I think as others have mentioned, the difficulty ramps up a little too slowly, and on my second life, I ended up getting a score of around 200 (once I started to understand how the health system works). Either way tho, it's a really neat concept for a game jam entry, nice work!
