Alright, a tower defense game where you're mobile is a thousand times more stressful and I love the idea! And Pulling off a not-difficult-to-understand 3D space in this short of time is a challenge I'm very impressed y'all pulled off. Absolute kudos. I actually ended up liking the high difficulty and scant resources, though I can see how some folks might find it too difficult. The minimap was an excellent addition I found myself using frequently. I've never seen it before and it was a simple thing that greatly improved the experience.
I wish there was a little more time to get familiar with the controls before the first wave starts, and I also feel like having a colored area when you try to place down the towers to indicate where they can or cannot go would have been very useful.
I ended up running in circles around my towers and that was honestly a bop of a time. :] Awesome job y'all.
