Awesome, that's great to hear! I managed to get into the leaderboards, but it's hard when you cannot build anymore, and when the framerate dips below 1 FPS... (I think one of the reasons the framerate tanks might be because you'll have 2000+ souls flying around you that you cannot spend anymore.) I'll be awaiting the update!
(By the way, are you rewriting it for DOTS / ECS? This seems the type of game for it.)
I also have some suggestions regarding game design (you can take it or leave it): around wave 50 (40-60), you'll be able to build an impenetrable end game fortress. Although wizards and queens are still a bit dangerous, the only real reason to lose at that point is if the game crashes (frame rate / no building possible). I think it would be great to introduce one or two more end game enemies at that point, to shake things up again. For instance one that can blow up your towers(!), or one that can fly over everything. Just to guarantee that the game will end at some point...
Also, with these very busy waves, it would be good to indicate what it was that killed you (which type of enemy).
Anyway, great to hear that you're still working on this game! I think it can become a real hit, especially if you add some ways to get more variety (different maps or waves?) or meta progression (ability unlocks?).
