Once again... to people having input issues, reassign your controls. Ctrl and shift are best, plus letter keys for movement. What's probably happening is your keyboard is wired in such a way that the inputs are interfering with each other, but most modern keyboards are designed so you can mash multiple letter keys (for fast typing) and ctrl and shift are assumed to always be pressed in combination with other keys, so they'll never interfere with anything. The same can't be said for the arrow keys or spacebar.
To the developer... you should probably change the default controls.
If you're having trouble with key responsiveness try remapping the direction controls to wasd or ijkl, and jump to a letter key instead of space. Worked for me.
Had some issues with the controls not responding and then I figured out it's because my laptop keyboard can't accept direction key + jump + jetpack simultaneously :\
Looks beautiful but feels kind of aimless - maybe some quests would help? Also maybe fix the camera on the bottom of the screen when you have more than one snowball, because otherwise there isn't really a good strategy for those moments besides wild button mashing.
I played the hell out of the first two games and I think this is the best one so far! One thing though, after 3 games, can't you afford some new music?
Ever since getting the hard badge, I've barely been able to crack 20 seconds on this thing. I swear to god, if it turns out I used all my latent psychic powers on a flash game...
