I can definitely tell that Risk of Rain 2 was a massive influence on this game (not a bad thing, I love the RoR series) but there are some spots you could definitely improve upon. First and foremost is that you don't stand still when using any of the player's drill attacks. It felt incredibly immersion breaking and annoying to have my flow interrupted because I (most of the time accidentally) triggered one of these two attacks. Secondly, I'd power them up a bit. I never really found a reason to not just blast everything with the gun attack (given most enemies fly and keep their distance). Finally, I think you could've integrated the spinner more thoroughly to reinforce the link to the theme (perhaps even as simply as just making it occur more often).
Despite my complaints, I did quite enjoy this submission and totally think it could be expanded upon after the jam!
fyi, a silly little dinosaur as a main character is incredible.
