Brilliant gameplay mechanic! Kinda reminds me of Cave Story (both in its underground setting, and use of a high-powered gun that can propel you anywhere), which is always a good thing. Graphics are very eye-catching, and the music is catchy and fits the environment. The various obstacles that are introduced throughout the game are pretty clever; the reflective metal surfaces forced me to plan my routes, rather than just blasting my way through. Kept me playing to the end (I got a time of 769.50). Lots of fun! Good job!
