The game looks very good! But I didn't understand how important the choice of buildings is. And how the shield actually works on the defensive. Also in the defensive phase, if the base is large, the scales at the bottom make it difficult to see the crabs. Anyway, well done!

Neat, I enjoyed trying it out. It's pretty hard considering the crabs' speed, but if you're good at defending during the first half you can pretty much just rest towards the rest, since the damage starts ramping up rather slowly. I also missed the point at which my HP stopped recovering automatically, but still made it to the end, with a score of, uh, 45 I think. Though I was just using 1 of each building type all along, I'd suggest having their descriptions on at all times, not just in the tutorial. All in all, I liked the gameplay concept, several difficulty settings and the simple yet pleasant to look at graphics. Nicely done!

Nice game!

Nice idea :)

At "normal" its getting pretty hard. the step from casual to normal is heavy..

Sounds would be nice also and some more effects.
