This was a really great game. It really didn't feel like it was missing anything. Good platforming, controls, art, sound, music, combat, boss fights, and GUI. I did suffer extreme frame rate droppage as I got higher. It rendered the game unplayable after The Rafters level. I'm curious if anyone else experienced that. It also would have been nice not to need to backtrack to buy upgrades whenever you don't have enough money the first time. Being able to buy upgrades at the flag would have been a great quality of life improvement. This game is one of my favorites so far. Well done!
