Good job on your first entry! I think as someone with little to no experience, this is already a pretty good entry. The game functions nicely, playing out as intended, with a boss fight and an end screen too! Not too shabby at all. The game is simple yet reasonably enjoyable, for sure would need some polish, but overall, this is already nicely done. The length is alright for a jam game (don't be like me making a game jam game needing 4 hours to complete), so don't worry about it too much.
Other things I like:
- Graphics are surprisingly nice and consistent across the game
- Pacing is good
- I quite like the curved path the axe took. Feel really unique among all other shoot-em-ups
- Boss battle is hard but not too unfair
- Level 2
Suggestions:
- Seeing all the assets used in level 2 makes me wonder why don't you put those in level 1 instead. It would make the game look way better
- The game screen is very small, which makes it hard to play without zooming in (but zooming in breaks the scene sadly :( )
- Bullets could be a bit larger and prominent, given that just 5 of them would send you a game over
- Some blinking/overlay effect for the boss would be great, to give some tactile feedback when you are damaging it
