I'm a bit of a sucker for anything Shell based, and I am glad to see this does not disappoint. While very much in line with the usual programming-for-newbies style of gameplay, I love the presentation and the need to actually use semi-shell commands and such, and the puzzles are pretty well made and fun to solve. My only real complaint is that the shell windows have to take up a lot of the screen, and while it is charming to have to manage screenspace like that (much like with my actual projects using the shell), it is a bit of a pain in gameplay. Maybe having some dedicated whitespace would be good? Overall though, the game is great!
