Want an easy way to earn money? Repeatedly kill the training bot in the first level, and only upgrade health. Once you have upgraded both your astronauts health to max, buy another one and upgrade the health only. Cha-ching!

To everyone out there: What is the point of crumbling ground? I mean, you can't stop. You can't turn back. You just keep running. So how do you fall down the crumbling ground? Is it just me or I think crumbling ground in running games are completely pointless? Of course, it could be passed as a "special effect."
It's a great concept, and can be a great game. Add a better main menu, sound effects, maybe items or more, being able to play online, three or even four players, different colored ninjas, and more. Hope you make a second one. :)
Going AFK? Still want to use the skills every minute or so? It's possible! Press "Tab" on your keyboard, until there is a square around the words "Class Skill".
