Customer Reviews

great game, controls need tweaking

Fantastic game. My only suggestion is that there should only be one button for "invert gravity" (or, better yet, a setting that recognizes a tap anywhere on the screen as a command to invert gravity). It's a bit silly to divide it up into two buttons that essentially do the same thing, and kind of distracting -- my fingers keep sliding off the tiny button area, resulting in death.

I heard of this game and picked it up as part of the Because We May sale. :] I had never heard of it before, and am glad I found it!

Fun little game-VERY DIFFICULT

Gravonaut is definitely worth 5 stars, however be warned- it is extremely difficult. But despite the frustrating difficulty it is still very enjoyable. The retro theme and PAL 9000 are cool, the boss battles are fun, and it is satisfying to finally beat a level.

There are 2 problems:
1- the game takes longer loading times than other games
2- the game is a little buggy. Periodically it speeds up at least 3 times as fast. Sometimes my character splits into 2 and runs around leggy. Sometimes my left arrow refuses to work

Overall the game is great. I like the mini games and unlockables


This is an awesome 8-bit game, with a classic feel and challenging levels. The only problem is on the 14th level it freezes, also my avatar will split in half and die, and some deaths count as two for some reason. Overall great game.
