I had so much fun playing this! This was the most addictive and engaging game I've played so far in this jam. I can't believe this is your first game!
The onboarding process that smoothly teaches players the controls and mechanics was incredibly elegant, and the difficulty curve felt really well-balanced—except for the final wave (My control skills aren't great, so I couldn't beat the wave where tons of jellyfish, seagulls, and obelisks swarm me. Haha). AIso, I appreciated that the color detection wasn't too strict. I think it would be even better if the difficulty of the final wave and the sound effects when defeating enemies were improved!
The story, gameplay, and presentation were all excellent. Though after playing this, I think I'll be scared of jellyfish and seagulls for a while. lol
