One of my favorite entries so far!
Really hard at first, but once you buy a few time upgrades and bullets, it becomes WAY more manageable and fun. I got all the way to the end, but I encountered a weird bug: I had to alt tab out of the game at one point and coming back, I would always do a default shot whenever I entered a duel. I could not get this to stop. This was fine in general, because I had enough health + bullets to do all combat but it soft-locked me out of the boss battle where you only get one shot.
Still, it's not a problem for anyone who doesn't alt tab so no points deducted for this. Really great entry, enjoyed everything about it.
