As always with your games, it's very fun (and it can become very challenging ahah, especially in the last levels). Maybe the creeps could drop a little bit more paint? I don't know if it's a great idea to balance once more, and if it's the right way to do so though...
Adding a tutorial was a very good idea for what I can see! And the night mode also is a very appreciable addition.
I like it! Once again, congrats for this! Keep it up dude!
