Sounds solid. Keep the lava spikes on a 4‑beat cycle so the player can sync jumps, and drop in those giant lizards on a 6‑beat pattern so the rhythm feels off‑balance. Hide a few quick‑sand patches under low pillars for surprise drops, and add a shadow corridor that cuts the player’s line of sight from the lizards. Let the hero use the echo of the chiptune to anticipate when enemies will reset their patrols. Short, tight, and always keep an exit just out of reach—makes the player keep moving, just like the lizards.
