Developer: Big AB Games
Robo Instructus welcomes existing programmers and newcomers alike, but I wouldn't consider it a casual experience. It takes a lot of patience and endurance to get through some of the more complex levels. The difficulty can spike quite early on, which may dissuade people from completing the game, especially if you are new to coding. With that said, the thrill of seeing all your work and code flow together to complete levels is exciting. There are multiple ways to get through each of the puzzles, so if you get stuck, you may want to try and think of a new approach.
