How much levels in the full edition ?
Over 100 (although not all are puzzles). Play time seems to be about 3-5 hours, depending on how much of the nesdev compo version you played (since those puzzles are in there too).
Tx and do you have a price range ?
Physical will likely be $65-70USD. Digital will likely be $10-20USD. Nothing firm yet though.
This high for the physical ?
Yup. It's sold out though.
