Not sure how much I like the blue rooms... They are so much easier than the tunnels, and when you get thrown back into a tunnel from them (especially at higher speeds) it's a bit of a kick, not to mention how much easy distance/acceleration you get off them, you barely even have to navigate.
Good game.. But between making sentrys and repairing, you get so little resources for upgrades... Not to mention how often you have to do this... Good, just.. maybe needs a little tone down.
Obvious sell towers needed, but I can't wait for this to get finished. Though I think the electric tower is kind of useless, even in the beginning waves... Even with the support towers. Keep at it.
