A creative use of typing and the character grid!
I especially love the way levels are presented and how responsive and seamless all of it is.
My only gripe with the design is that it is very undo heavy thanks to relying a lot on finishing the commands at the right point and counting where words will end up or if they fit at all, which is not really an interesting aspect of the game I think.
While it might take away from the simplicity a bit, I’d like to see how an autocomplete-like feature would work like that would print (with a faded color) the started keyword ahead of you so you wouldn’t have to type it out or count cells before typing to realize it won’t fit or if you’ll finish the word too early. So you type l and it shows eft ahead of you and so on. Maybe you could use tab to complete but the main point is the preview itself, not the completion.
Anyways, great entry that could definitely be expanded with more mechanics and levels!
