Gives me Geometry Wars vibes which is cool. Pretty good idea on the theme, on my second play it became obvious that I was using up all my life shooting. I think it has room to expand further. 

For feedback, there were a couple of issues with screen sizing and UI going off the screen, and gameovers keep the play in motion where I have to refresh the page to replay. I also kept losing my mouse off the screen, I think you can lock it into the screen for better gameplay. If you take this further, I'd recommend adding several shooting sounds, picked randomly for every shot to add variance.

The game keeps updating after gameover.

Other than that, amazing work, feels amazing, looks really nice, catchy music.

Gave 5 stars.

I like how you interpretedd the theme for this jam. The game feel smouth and music is quite relaxing. For my own taste, the game is toooo easy, it require a proper balance to keep the player in a flow state. Also, the only stat that seems usefull is damage, but it give you to much of a advantage for the cost. Overall, good job.

Nice! Not bad at all regarding it's your first game ever. Cool neon style. Intuitive WASD+mouse control

I liked this one, I hope it doesn't fly under the radar

Cool game! I love art style, and the idea is very original! Very well done, especially for your first game! :D Although it was quite difficult to aim, as my mouse kept freezing, but that might just be my computer :P Anyways, I enjoyed playing your game, keep it up!
