What players say

Players say it is a well-made throwback to classic platformers like H.E.R.O. and Dangerous Dave, with tight jetpack-based movement and a one-hit-death system. The level editor gets frequent praise. Players split on how punishing the instant-death traps feel, with some calling it satisfyingly hard and others finding it frustrating.
