I got really addicted to this. I was spending so much money on healing towers that I didn’t really do any upgrades, but I managed to beat it (I think? The enemies stop and the game just ends at some point and you win right?). I should try another run with upgrades. This is a really fun game, I think it would play really well with a top down view on a 3d world, hopefully you keep building on this.
Awesome submission, thanks for sharing. My game is linked below this post if you want to check it out.
