Needs a, "Are you sure you want to sell this", a "Are you sure you want to restart from last checkpoint", etc etc. I accidently pressed both of those...
Normally I'm not a fan of puzzle games but this game is extremely fun. I found some puzzles challenging, the story was great, the soundtrack fit the game, the graphics fit the "hacking" story line to make it a puzzle and overall I have to give you a 5/5.
