An incredible amount of polish for a three day jam. I usually don't like matching puzzlers, but this one won me over. The visuals from menu to shop screen to gameplay to credits are all top notch. The music hits the theme, of course, and one extra track snuck adds adrenaline at the right moment. There is plenty of time to think and consider moves, and then also consider future moves on top of it. And as the upgrades progress, so to does the gameplay loop. What starts as trying to just make big chains turns into trying to find ways to hit enemies and get rainbow gems while avoiding ending in safe spots. The final upgrade surprise added a whole new layer just to cap off a great experience.
