it was a great game, i expected a boss fight at the end cuz i was constantly getting more powerful but didn't encounter anything to test those new abilities, (i think you probably planned to do that since there are extra missiles right before the end). At least more enemies in the second half would have kinda (maybe) fixed this cuz i feel there were more enemies at the beginning than in the latest zones. But the level design i think was really good, i enjoyed exploring each zone and finding secret walls to break.
PSDT: i like your illustrations a lot and i just realized it's you. Made me happy to find you here. Congrats with finishing the game.
