A typing game and typing test where your speed is heat: type fast and clean to climb the Scoville scale from bell pepper to Carolina reaper, with combos, streaks and fever. Modes: sprint (10, 25 or 50 words), blitz (15, 30 or 60 seconds), zen (endless, no clock), survival (a fuel clock that drains faster every level), floor is lava (words fall toward rising lava; type them before they land) and hot pursuit (a cop chases your caret down the text you've typed; a wrong key stops you cold). Survival, floor is lava and hot pursuit start from the level you pick. Personal bests are saved.
