I really love the game, but I honestly think that it's a bad design decision to take away instructions in later levels.
There are levels that cut away just the "calc" intruction, or the entire communication (tell / listen).
Since these levels are kinda advanced already (like sorted defrag for example), I really don't get why you have to artificially make it even more fiddly and complicated by removing parts of the toolbox the player already learned to use.
Something that also bothered me in "HRM" already - WHY does the editor not offer even basic copy / paste? Limiting it to only copying the entire solution is really strange, since the only thing it achieves is introducing tedious repetition in some solutions that could be avoided.
Repeating whole blocks of code with just very minor changes for each if result is not fun. This is a game, so making it harder and less fun than using any code editor is a decision that I fail to comprehend.
