One of the best games of the jam, for sure. And the best tower defense, for sure (at least from those I've played).
I loved almost everything: the visuals, the water shader, the variety of towers and enemies, the progress curve.
The story was also very well constructed.
The fact that you have to collect trashes during the waves makes the player always moving and watching. It kept me active during the whole game, unlike a lot of tower defense where there is a build phase and then a wave pahse where you look at your defenses shooting.
Impressive work, really!
One (very) little downside: some collectable trash look exactly the same as the enemies, which can be confusing sometime.
Really a GREAT game. One of the few that I've rated 5 stars (and I've reviewed more than 200 games for now).
Bravo!
