I definitely had performance problems.
This game was great! The movement systems in your other games are so good, so it's not surprising or disappointing that you release a speedrunning game, and one that still feels very unique and interesting. I like how the story is hinted at, and the visuals were probably the best in a minor-key-games work to date. If this cost 3 dollars, I probably wouldn't have been disappointed if I had paid for it.
