In Hazmat you operate some small pinkish, alien looking creature. Steering is using the arrow keys. You can double-jump by pressing 'up' twice. And steer while in flight. View is 2D, you'll have to jump from one platform to the other to reach the exit door of the level, evading toxic pools and such. Graphics are pretty basic and resemble the old arcade games like on C-64 and ZX Spectrum.
