Normal mode is a good way to get used to the controls, and then hard mode becomes a delightfully evil precision platformer in the vein of Super Meat Boy. I like how it remixes the levels, turning the huge stretches of empty space they once had into lethally unsafe ground. The short level length and tight controls make what would otherwise be a frustrating game fun to master, and the very small sprites, while they'd be hard to see on an actual Game Boy, also remove the issue of screen crunch common in many platformers of the era. I was originally going to give you a 2 for sound due to the lack of background music, but hard mode made me bump it up to a 3 — the grim 8-bit ambience in the background is oddly fitting for watching a cute blob die a thousand and one deaths through being impaled on spikes.
