Awesome work! Beautiful and well-designed. Very nice to see Construct 2 games like this.
I have a Windows 8 tablet lying around and I ran it on batteries (Intel Core i5 @ 1.6 GHz (x64), 4GB RAM, Intel HD Graphics 3000). It wasn't quite 60 FPS smooth, seemed in the 30-50 FPS range, but still perfectly playable and enjoyable.
