Aww, what a gem this one was! Next time, I'll make sure my glass bottles get thrown directly into the ocean so those coral reefs can get +10 energy ❤. (just kidding)
Seriously though, this has a great message, and the game itself is legitimately fun! I'm impressed that you guys made all these models, that's quite a lot!
I did have a game-abusing moment occur that I leveraged to win after I got utterly annihilated during wave 4. One of the minions got stuck in the main base and wasn't moving, and my only tower was an urchin that couldn't hit it. I decided to let the minion sit there while I farmed trash for a while, giving me the resources I needed to go into Wave 5. On the one hand, I shouldn't have been able to do that, and on the other hand, I felt like I needed to.
But gosh, for a game jam game, this is very impressive work! Loved all the little story moments between each wave, and while there are some game design tweaks I'd consider, I think overall you did a wonderful job!! :)
