Recommended because it is free

It is mostly-well-designed, though it does have a lot cheap run-enders that are unavoidable. Those kamikaze enemies are practically impossible to avoid, especially while fighting an enemy. Slow upgrading and resource-grinding mechanics with cheap, quick deaths make the most frustrating experience possible.

This game is obnoxiously difficult even when you play on Easy. Yes, it is one of those "easy is hard and hard is also hard" games. There are some minor upgrade stickers you can unlock by dying after killing a lot of people. Those random people you accidentally run over - they are your free upgrade points. :)

It has some style, though I wish it was more based on skill and dedication to win instead of nigh-unavoidable deaths by game design.
