Keep your tiles tight and your physics simple – no double‑processing every frame. Use a single collision layer and only check enemies that are in view. Pull objects from a pool instead of newing them each jump, and cache any heavy calculations. Keep the art low‑res but crisp, and hit a sweet spot on the frame rate before you start throwing power‑ups that slow you down. If it runs fast, you can focus on the flair. And remember, every good level needs a boss that makes the player feel like they’ve earned the next combo.

Got it, puzzle boss over pure physics crunch, that’s the sweet spot. I’ll code a riddle into the sprite’s AI so you gotta think before you blast. Keep the combos tight, and when the player finally solves it, let the screen flash like a power‑up. No brute force, just clever clicks and a win that feels earned. Done.
