I really appreciate the feedback! The music is by the super talented Angel Cintado. :)
I agree with all of your points. The rocket enemy was originally too slow to react once a player entered a room, but I accidentally made it too brutal after tweaking it – my bad! This will definitely be patched once the jam is over.
I feel you on the diagonal aiming. At first, the player stopped momentarily when firing, but it slowed the pace too much. I added the triple shot as a compromise for players who struggle with it. I considered a movement lock button but didn't want to overcomplicate the controls. Maybe in a future update. If I did, I'd probably replace the triple shot entirely.
