I think the game requite some tweaking on the visual part(and maybe a little bit on the gameplay - adding some fast forward button would be nice).

That said I think the idea is pretty neat, it just need some tinkering around!

Interesting idea.  Could have used clearer instructions.  Was there a way to add new towers?  I only ever used my original two and they got taken down pretty quickly.

interesting seed of a concept as a unique twist on tower defense. I don't have too much to say but it seems to have a lot of potential to expand. I agree with another reviews that some additional ui indication could be a benefit. i felt the minimalist sfx and music worked well together. i had a fun time while i played it!

Good concept, nice retro=style art and sounds. Would work great with touch screen. Maybe there should be indicators of how much power left in orbs.

Nice tower game!
