Good toy factor, much fun to interact with. Lovely presentation, only the mountains feel flat. Not sure if protagonist male or female (not that that's a bad thing in itself)
Nice variety of fun enemy units. Large ones are hard to tell apart as color patterns quite similar. Bikes often crash into things.
Initially I felt there should be a short range radar of some sort but quickly got used to it not being there.
Enemy units play similar in the sense that you can deal with them in a similar manner every time. Perhaps some support units that slow you down or call in backup or shield others (reflect bullets?), or having to stand in one spot (to recharge?) or defend a structure until its complete would provide tactical variety.
You can just zoom around carelessly and bump into everything as no static mines or things to avoid. With current threat level this makes game quite easy once you get the hang of it.
Enemies stopped coming at one point tho I guess that is very WIP. Loved the sport courts in that one base. Really enjoyed exploring the map to find the objectives. Would be great if destroying things in bases had gameplay impact (disabling a barrier elsewhere, dropping health/powerups, etc)
