Nice find. Pixel art is great for nostalgia, but a cartwheel cat is too on‑the‑nose. If you’re going high stakes, you need a mechanic that ties the cartwheel into risk or reward—maybe a timing combo that unlocks a hard mode or a secret boss. Also, think about how the cat moves in the game world. Is it a platformer, a fighting game, a rhythm challenge? And don’t forget pacing; a single silly sprite can’t carry a whole title if the core loop feels shallow. Work it into a clear concept, test a prototype, and then see if the “wild” part actually adds tension, not just gimmickry.

Sounds solid, but watch the risk‑reward balance. If every miss falls you into a glitch, you’ll get a negative feedback loop that kills fun. Make the penalty feel like a challenge, not a penalty. Also, the secret door popping for every spin is a good hook, but the mini‑bosses need unique patterns so the combo actually matters. Hard mode laser cat‑food? Nice. Just remember to keep the timing windows tight and the audio cues clear—no one wants to play a rhythm game that feels like a glitchy dance. If you run a quick playtest, watch for moments where the player feels “I should have done that” versus “I nailed that”. That’s the difference between a slick risk‑reward mechanic and a frustrating glitch. Good approach, keep iterating.

Nice tweak. A shaky spin that still gives a boost keeps the rhythm flow without breaking immersion. Make sure the speed boost feels worth it—if it’s too subtle the player won’t care about the miss. Signature rhythms for each boss is good; just keep the patterns distinct enough that a single timing error changes the fight, not just the damage. When you run the prototype, log the hit ratios and see if players are actually aligning with the beat or just guessing. Also, watch the audio—synth bass is fine, but it needs a clear offset cue so the player can anticipate. Keep iterating, but stay tight on the core loop; the rest can be polish.
