After about a year of work the full version of Rollin' is now available. It has 8 different levels (*cough* and a hidden level *cough*, 10 unlockable characters with unique abilities, and splitscreen multiplayer. The game is available here for £1.49 ($2.34): Sellfy.com
I'll be updating the game with bug fixes and such but otherwise I'll be focusing on other projects.
Big thanks to Ninja Sex Party, Holly Conrad, and Ross O'Donovan for being playable characters, and thanks to the Game Grumps community for beta testing and giving me feedback over the past few months!
This is the first full game that I've made and since starting it I've learned a lot, and so while this game isn't amazing or perfect, I'm proud of it and I hope you guys enjoy it for what it is.
