Super adorable and really fun little game!! I love these kinds of games where you're playing the same map every time, but slowly unlocking more upgrading/skills. The music was nice (sounds like Bosca Ceoil? In my experience it's hard to make music with it that isn't super grating, so extra props for that lol) and added a lot to the atmosphere. The only thing I would mention is I wish you didn't have to restart from the beginning after getting hit once :(
For your first game, this is extremely impressive and I'm looking forward to seeing your future stuff! Great job!
