I absolutely agree with you.
Once I got one of my friends to playtest it, he immediately did the strategy to stand on top of the bauble and accumulate enemies below hahaha! I chose not to remove that feature though because I wanted the arena to be more than just a flat area and for the player to have a fallback option in case they got too overwhelmed, that'd initially be in the form of an area-of-effect attack but I didn't have the amount of time necessary, so the easiest option that I thought of was for the baubles to stay
I'm very glad you enjoyed it! And thank you for the feedback, I very much appreciate it!
