Really cool concept and a novel take on the theme!  Made it to 10 waves using the bubbles on the enemy projectiles to thin the numbers.  Would love to see this concept expanded on.

Huge plus for the Pico-8! I really like the idea of bubbles. It is fun! :)

I love to see Pico-8 stuff in jams. Pretty fun, lovely sounds, nice art. A bit lacking in terms of gameplay since you can just spam both keys but it was still challenging for a stupid and slow player like me. Solid for 3h30!

ye the game idea is cool but i think its executed not at a game jam winning standard. also the begginig levels are hard and also you can just spam the shoot which kinda makes the difficuty of the game a lot less. i would suggest starting off with the idea that you can just spam but later you only have like 10 shots. tale anything i said with a grain of salt. if i hurt u im sorry just some friendly feedback(:.
