brohocho,you can replay levels to earn upgrades.Just click menu and click the level you want to repeat.I'm now on level 35.Five to go:)Not a bad game.
A tip to get to the second third level,be accurate and don't use mines or airstrikes.They will stockpile and when you have a lot,blast the hell out of everything:)
Fantastic!Well done.Not random outcomes at all.Match your colour attacks to the colour bar over the enemy.This is a very well made and entertaining game.
Thanks so much!
