very clean aesthetic and creative concept! i managed to beat it on the first playthrough and had a lot of fun
not sure if it was intentional, but the 'render distance' seems much, much shorter on the dark side--made visibility extremely limiting and made it really obvious when enemies were spawning just outside of that radius, which felt just a bit cheap to get hit by. i also think the ability upgrades could use a bit more variety, just to spice up future replays
overall super sick game tho, really doesn't feel like a 3-day project at all!
