More power ups were on the wish list of things we wanted to add, but unfortunately time didn't allow. Only 72 hours, oof! Thanks for trying our game.
To your point about different controls, we debated adding a "space bar" jump command to make vertical movement easier, but after several sessions of playtesting and getting used to the physics we started to find the tradeoff of shooting & movement being on a single control created some really interesting gameplay moments. And, with practice, it's definitely possible to get some really compelling moments from the existing controls that mix skillshots with finessed movement. The highest score we've seen so far is 135k (about a 10-minute session!) So, survival and mastering the conrtols is definitely possible!
