Is this a troll game? On the first puzzle, the turtle never chooses to go right when it hits the '?', so it never reaches the exit. It should do that, right? Or am I dumb? I understood that it sent you randomly in 4 directions. I would expect it to go right at some point if that's the case.
Well, in the case that it's not a troll game, I'll leave some criticisms.
It took me a while until I understood how the 'Editing Station' and the 'Full Funge' worked together. Like, at first I went to the 'Full Funge', which was what I assumed to be the 'Integrated Machine' the tutorial mentioned, and pressed 'T'. Nothing happened. Then I pressed 'Tab' which was the other thing the tutorial mentioned. Nothing happened. From then I started pressing everything until I understood how it all worked. It's definitely anti-intuitive you 'begin playing'/'begin editing' the board somewhere, and then actually edit and see it play somewhere else. Also, should the RMB do something? It says 'Select' when you hover over something.
When editing the board, please drop the double cursor. I often couldn't tell which one of the two was my real cursor. I understand that you need to convey the direction somehow, but in that case, you should mark it with an arrow or something more subtle so that the cell you're selecting is unmistakable. I'd also consider dropping the cursor direction altogether and making it so inputting a character doesn't move the cursor. But I'm not really sure which would be better to be honest.
Oh, and I spent 10 minutes looking for an upside-down ^ until I realized looking at an ASCII table that there was none and that it was actually a v. So yeah, that happened.
I'd also recommend making an easier first level. Like, I'd introduce the 'skip' character in a second or maybe even a third level. Because I honestly forgot about it because I was just learning how the game worked in the first place.
But anyway, it looks pretty interesting. I'd be down to play more if I could get past the first puzzle. Like I want to know what those sockets and all that stuff are for. I can tell the mechanics will get spicier. So yeah, good luck, man. I hope I wasn't too harsh.
