I just pushed a new update with the XP system and a few basic upgrades. I wanted to make it richer first (more upgrades, better upgrade screen etc.), but I decided that you shouldn't wait too long to see it - so here it is. Check it out and let me know what you think, while I'm busy making it better!
Changes:
- XP system added, gain XP by killing enemies. Bigger combo - more XP
- Choose one of three randomized upgrades on level up
- Added handbrake sounds
