That was a lot of fun! There are some bugs with selecting upgrades, and having an upgrade get stuck, which almost made me ragequit, but then I kept playing and had a blast. I got to wave 25 before I decided by base was effectively unbeatable.
Awesome!! Thanks for letting us know about the bug. We've got a fix ready but we can't upload a new build until the jam is done. So glad you liked it. We're working on more traps, upgrades and enemies, so hopefully you'll come back to enjoy a more balanced game in the future :)
