Nice-looking game... sadly it's incredibly boring and repetitious. Upgrades cost way too much and weren't really what I would call "upgrades"... they were more like bare necessities to play the game on a basic level. The jump upgrades were ridiculous... a little higher, now just a tad higher... yay. The only 2 upgrades that were warranted IMO were the butt drop and the Anti-Grav which were needlessly split into 3 separate upgrades. The game should have started with most of these already in place... and instead had fun upgrades that enhance the gameplay (instead of taking it from unplayable to playable) like a double-jump, a dash... maybe a weapon and some enemies thrown in here and there.
Basically, I feel this game's a complete waste of time... by the time (hours) you get enough upgrades to actually play, you're already sick to death of it & there's nothing to look forward to.
