According to a comment posted by the developer, Crayon Physics Deluxe is to be sold at USD $20 on the Kloonigames web site at when released. A Windows version will be made available first, with ports to perhaps Linux or Mac to follow shortly thereafter.

No confirmation yet on whether Crayon Physics Deluxe is coming to Steam or any other digital delivery service, but the game itself will have no DRM software whatsoever. (old video of Crayon Physics Deluxe shown above)
