Greyskull meant you posted on the wrong thread which bumped the Sale Thread which misled other users to think the game is on sale for free again. There is a Sale Thread (this thread) and there is the game discussion thread. That said, Touch Arcade Forums is a public forum where not every game's developer is involved in, and there isnt a guarantee that a dev is even aware of the existence of the game's thread in TA, although it is greatly appreciated when they get themselves involved with us.
Still not free yet. About sonic CD it is great but I have a difficult time using controls w/o the feel of the buttons. The actual control of the game is perfect
