You will eventually get overwhelmed (I think wave 10 is around 500 heroes spawned, one every 0.1 seconds), but yeah the strategy is lacking too. Learning Godot was trickier than I expected as I had to unlearn over a decade of Unity habits, so I had to pull back on my initial idea. What I had planned to do was give the player something like 6-9 different abilities that’d randomly cycle as you gained experience and leveled up (from killing heroes). That way you’d’ve been forced to play with what you had instead of just spamming the best abilities.
I’m strongly considering making this into a full game. But I think I need to go watch some more godot tutorials on how to best structure a project for workflow first 😅
