I swear I commented here when I played this after the game jam first ended. Whoops!
I enjoyed this game and it was nice to see someone using the plane pack for this style of game. When I first saw the upgrades I immediately started saving towards the "Hold To Fire" upgrade haha. I don't know if there was an end to the game, but I maxed out all the upgrades so I count that as a win.
Good job!
