Hoo boy
This was pretty fun, although I do have at least one complaint.
The blind long-jump before the Rocket Riser?
That is patently, undeniably, bad game design. It would be a perfectly fine jump if the screen could scroll Mario style, or if the landing spot were visible. As is, it is just a terribly designed bit of player-hate.
Also, the music gets a little grating/old, but the mute option makes that relatively moot.
