Glad to see these details being noticed! After the voting is done, the game is going to receive a robust update, with more polish, and levels that are going to explore the main mechanic a bit further.
Much obliged! More work is definitely being put into it! And yeah, I'm still thinking about a way to make the gas state have some drawback, and your suggestion is interesting...
Thanks! Yep, I'm definitely more of a programmer than an artist. After the voting is over, I'm planning on fleshing out the game more, that also means more levels!
