This game was incredibly well polished! The Art was solid and cute. The Audio was immersive and fitting. The UI design was great as well, I might have to take some notes :)
Also - this game did bullet hell really well where it's easy to go wrong. The bullets were slow and dodgeable, allowing the player time to avoid damage. The number of bullets on screen were sparse at first to give the player time to acclimate to dodging but ramped up over time to increase the difficulty
For a 7 week project, this was overall amazing! If you guys plan to keep releasing updates, I have two recommendations:
The game could use some sort of variety to spice it up! That could come in the form of powerups, weapon upgrades, new enemy types, or even bosses. Doesn't matter exactly what it is - that's up to you guys!
The game could use some sort of progression system! Something to really incentivize players to play many many runs would really help to improve the game! This could be in the form of an end goal (beat boss 4 and you win the game) or in the form of unlocks (get this far and you can buy xyz), etc.
Nonetheless, this game was an amazing experience for me!
