Thank you so much! I'm really glad you're enjoying the game, the skins, and the art style! It means a lot to me, especially since the game is still a WIP and currently in Version 0.0.8.
And thank you for pointing out the achievement notification covering signs! That's actually a really good catch. I'll definitely look into making it disappear faster or move out of the way when there's text on screen.
More levels and content are coming, so I hope you'll stick around for the full release!
And yes... a dog rolling. That's exactly the idea!
