Very cool wave-based defense game!

It took me a little while to figure out how the ammo-types work together with targeting enemies, but once I figured it out, it made a lot of sense.

Like avit0r said, it is pretty tough to lose. It'd be cool to see an escalation in difficulty, or variation within the arcade games. Or even some special attack abilities!

Well done!

had fun, but really hard to lose, could use more options.
