Looks like a cute start! I feel like you have something very potentially interesting with how "capturing" spawners works, even without any kind of "spawning" mechanic yet -- it seems like trying to figure out efficient "loops" to maximize how many you have captured at once before any revert back to "uncaptured" could be an interesting puzzle. Maybe hitting a certain score threshold permanently unlocks new paths, allowing for better and better loops over time?
Do you have any plans to make "sneezing" a game mechanic, or is that more of a "reward" for capturing enough spawners?
The one thing I really longed for was some kind of map or mini-map, to help me plan out routes.
Adorable art style, too! The how-to-play screen is really cute.
Good luck with your plans!!
