I managed to finish the game (only main puzzles). I really enjoyed it and i'm still thinking about going back to it, mainly to complete the optional branches, most of the challenges had me stumped and with a feeling of "i must be missing something obvious".
It's pretty cool that the developers took the time to make the solutions copy and paste-able into the game :p. I actually managed to paste your solution even though the formatting is messed up.
Tips for this particular puzzle: You are selecting regions of code based on the input signal. You could cut a lot of code, the SUBtraction + check negative method still works for a - and - pair of numbers and it seems that no input has mixed signals.
second tip: if you SUB a previous number you can restore the newest by ADDing. It is possible to save steps and memory by doing this.
I watched the first episode, here's a thing i don't get, is this a retelling of the last movie? I thought the movie was pretty lame, mostly because of super fanservice plot, space egyptian cat is alright.
Also just imagine goku having a normal-non-super-power kid, he would be dead by now, you just don't let your kid drive a tractor near a cliff.
