Had a blast!!! The gameplay is so gripping, im a huge fan of battle systems with a small number of synergetic weapons (just like ultrakill!) and it was very fun to beat the two bosses and zip around with the great movement (hammer alt plus left click my beloved)
The music was super fitting. No notes. Big fan!! Well done rockii!
The style is consistent and cute. I actually quite like it!
I now know first hand how much work it is to get voice acting for a game jam, so props to you!
The boss patterns were great for flow-state. Nothing too crazy, but still challenging enough to keep me locked in.
I think there should definitely be more feedback for hitting a boss. Have their sprite flash white for a quick fraction of a second, gimme some screenshake, and definitely a sound effect. Same goes for getting hit too. Having to look at the health bar the whole time just to check if I'm doing damage makes it hard to dodge bullets.
Edit: forgot to mention, I'm also a big fan of the atmosphere. Not to mention the intro cutscene goes super hard!
Overall I'm very impressed! You showed this off during a discord call the other day and i was already a fan back then, this just proved my first impression very right! Thank you for this cool game, I think you could definitely make something very cool with what you've learned and done here :D
