A tower defense entry. That is pretty cool. It was quite easy, though. I beat the game on my first attempt just by building blue tangs as soon as I made enough money for it, and I think I only had the reef breached once in the early stages. Other than that, growing defences is an interesting application of the grow theme, and I liked the overall idea of protecting marine life by fighting against plastic trash.  I think the game could be made a little harder, as it seems like  nothing could beat the simple strategy of just building the most expensive tower once you make the money for it.

The art looks really cool.

Pretty solid entry, I liked the theme interpretation and the incremental upgrades between the waves. I would have like to see some more enemy variety or maybe some more tower options but time constraints and all that. Overall a very good job!
