If you accidentally (or not) throw it backwards and it crashes your browser, here's how to pick up where you left off. Play the game in it own tab. If/when this happens, close the tab and DO NOT CLEAR YOUR HISTORY. Just close the tab and wait. If you can still hear the music, wait until it stops, then reopen the closed tab and pick the slot you were using. It should reload with all progress and upgrades.
Okay, bugs aside, lovely little game. The light effects and music make for a great atmosphere. The upgrades add depth to the gameplay and their prices challenge you to prioritize strategically. Also lots of fun to mess around with speed and altitude. Great job overall.
I echo 00r3d's post. Fun little game. Pretty. Simple. Nice music. Cool upgrades. Beat all levels. Just tooling around now. Not a single achievement. What's up guys? :?
