Wow. This is an impressively deep computer system you've programmed. The attention to detail is impeccable. The lessons are a bit dry, but then again, so was any documentation on programming back in the day.
I see there's some other more visual elements deeper in the game that I didn't get to. I only played the demo.
I'm gonna level with you. As a professional programmer, this stumped me. Mostly because I don't work with low level stuff like this. The logic is straightforward but the input and output data structure with binary that I'm attempting to solve for eludes me.
This is an incredible opportunity to teach programming through a game, that's kind of what I thought it was when I first opened it. While it can teach programming, my one criticism is it's not very accessible. i.e. I can chuckle about it because I already have years of experience programming, but if you were to hand this to someone who doesn't, they would likely not be able to figure out that the lessons are just informational and that they need to scroll down to the task and write the correct code to create the output they see on the right.
Basically what I'm saying is this is definitely a programmer game for programmers, and that's probably your only intention with it. It would have been cool if it was a programmer game for everyone though. That's just my opinion.
Overall, excellent game, very well executed.
