Incredible Cool Idea!
But the implementation could be better.
The User Interface covers to much of the actual Game, i would suggest maybe half the Code Editor Size since you don't need like 100 lines of Code at once, as well the "Documentation" on half, you should have then the whole half upper/lower screen for the Actual Game.
Instead of only Clicking the Code to copy it to the Editor, you should consider about making the whole Row Clickable to insert the Code in the Editor.
I also would love to have a quicker Reset of the Code Editor like a Right Mouse Click to Empty it instead of clicking inside the Editor mark and delete everything. Gets annoying after a while.
Overall since its a User Interface based Game, The User Interface must be "Perfect" at the moment its hard to read, because everything is transparent and overlapping. The Blue Color is hard to read.
The User Interface also bugged out at some Point: couldn't see half of the Stuff anymore.
I think this Game really has potential for much more!
anyway Great Work!
