This was a very fun shooty platformer. I especially liked the sound design. I can't put my finger on it, but the enemy hit and player death sfx hit me in a very good way. I also either found a softlock or I'm doing something dumb. If I die to the first boss, I can't jump further without jetpack fuel and if I go backwards from the checkpoint to get more, I can't jump far enough across the lava to reach the fuel powerup.
