Platformers, the genre that punishes sloppy code
Platformers have the highest skill ceiling of any major HTML5 game category. A platformer lives or dies on the quality of its jump arc, the precise relationship between input timing, character momentum, gravity, and friction with the ground beneath you. Get it wrong and the game feels broken. Get it right and the game feels like it could only ever have been this way. Browser platformers historically struggled with this because of input latency. Modern browsers have closed the gap, and the better entries actually rival their native-app peers.
What I look for: a jump arc that feels deterministic (you can predict where you'll land), collision detection that's generous on edges in the player's favour, level design that introduces mechanics one at a time before combining them, and checkpoint systems that don't punish you for trying to learn. Platformer catalogue below covers classic side-scrollers, single-screen physics puzzles, vertical precision climbers, and one compact Metroidvania I keep recommending.
