Thanks!
Glad the execution of the idea is to your liking.
With removing enemies, are you referring to removing them during the enemy placing phase or when you're trying to complete the level?
For the enemy placing phase, maybe adding an 'enemy' that instead deletes an enemy would be a neat addition, actually - sometimes you get screwed over by RNG, and it'd be an interesting risk-reward situation to try to get that enemy-deleter - by getting through placing more enemies!
As for the level-completing phase, I had a playtester mention that they feel like it'd be fun if there was an enemy that would just delete enemies it moved over. I think that would be a cool addition, too!
Thank you for the feedback!
