I fixed the issue with the UI, if you're down to try it again it would be much appreciated!
Nice! Working for me again on the web build on windows on chrome. I experienced minor frame drops / audio sputtering on the later waves but overall things felt really good. I like the variety of the enemies and how they challenge you in different ways. Nice addition that you can see what enemies are coming next and also I benefitted from the warning of "that timer's looking dicey" when I took to much too fast. Well done!
