Quite fun. Game is interesting mechanically, based on bouncing around at various angles/speeds. Controls are simple and intuitive but also bring an element of skill, which is excellent. Game mechanics are slowly introduced throughout the included levels making learning intuitive. Level design is the only element that holds the game back; the most interesting maps were those that acted as puzzles, which were mostly towards the middle of the level range. For other complaints, the ability to switch between a character/mouse oriented camera would be greatly appreciated for planning routes, as would allowing the slow time ability to continue through grappling.
Art direction is good. Enemies and danger are obvious, and their styling works reasonably well together. Music also fits the space/high tech theme. The only complaint here is static spikers are not immediately obvious to be on one side of a wall or the other when moving past them quickly.
Overall, the game is fun with the primary limiting factor being only 12 levels available. Secondary limiting factor is the limited size and number of mechanics seen in any particular level.
Bugs: One pulled myself through a wall that wasn't capped off at the end. Once bounced off a wall and was flung off into deep space at mach 15. Given the nature of the levels, I just reset them and lost all of 10 seconds. Overall a minor concern.
