Really well made, inspired, tower defense! Beautiful theme, got all the way through. Fun variety in the "towers" and cute story going on between waves. Cool variety overall. Great design to keep us picking up trash to get reef power, keeps us occupied while the coral reef is doing its thing. Nice visuals, felt like underwater, cute fishes and good looking vfx.
Got some framerate drops sometimes, for example when I spawned my first eel. Hard to deal with for a jam but fyi!
I also agree with the comments below that I definitely clicked the enemies when I thought they were trash. I'd like to add on to that, that I had hard time distinguishing things overall when there were many enemies on a tower and the healthbars layered on top of one another.
But hey the fact that these problems exist is a feat, almost a complete tower defense game made in a week. Love it guys, great job.
