This game is fantastic, very orginal!
5/5 for main game mechanics
The introduction and plot isn't the finest, try doing something to spice it up
The movement is... Good, not the smoothest, but very responsive.
4.5/5 for movement
Music, personally is a bit reptititive and sometimes annoying, a individual SFX and music button choice would be welcome.
2.5/5 for audio quality and choices.
Power ups are very fun and make the core of the game, the jetpack is my fav :P
Very original and fun power ups 5/5
I haven't encountered any bugs so far, besides the movement being a bit... Spazzy, at rare occasions.
Bugs impact rating depending on the bug(s) severity
Endless mode - Perhaps add a mode where it keeps going higher and higher and never stops... Or stops at a extremly high point. You either start with all upgrades purchased or nothing purchased, meaning its only you, no power ups
Beast mode - Your jumps are super high, all upgrades unlocked... Also in the mode the jetpack would be very fast and agile :P
Expand on the story - Add in more of a storyline, perhaps add voice actors, do something, the storyline is very plain.
Good luck with the game, if you do make any big updates, please msg me, I would be happy to play it again :)
