Since this is basically just an implementation of an interpreter for an esoteric language, I thought I'd mention esolangs.org for anyone interested in that sort of thing. A reviewer mentioned the small instruction set being limiting, but really the low instruction and data space are more limiting. See e.g. http://lodev.org/esolangs/braincopter/lk.png which is a text adventure in a language with 11 instructions total (no operands, so significantly more limiting than tis-100).

I was once interested in small limited languages that were stupid but funktional. Like brainfuck, whitespace but also few more user friendly. Mainly I tried to make my own language that would translate to one of these absurd languages. I didn't get too far with any attempt, but it sure is fun.

Before buying this game I did notice few open source Tis-100 "emulators" on Github. I haven't tried them myself yet, because I'm still on middle of the game, but once I finish I might give them try. Surely they can't be 100 % the same, but there is great potential once someone hits the spot.

And actully this Tis-100 language greatly reminds me of the Logo. It is much more fun than just kids moving a turtle on screen.

(Sorry if this comes double, I think my browser ate the the first but I'm not sure)

Actually this Tis-100 reminds me a Logo in Assembly disquise. The logo is much more fun and interesting than just kids movin a turtle on screen. Both are about writing the very basic steps in sequence to get a result from relatively complex task. With Logo the result is often a mathematical graphical shape and with Tis-100 it is the silmple yet elegant process how data is handled in limited enviroment.
