This would be a bit less hassle to play if Itch didn't interpret my pressing the down arrow as a scroll input but other than that I love this
Steam version of this is pretty good and free, if that would work for you, otherwise I found some code to disable keyboard scroll online, then made a bookmarklet out of it.
If the game developer wants to fix the problem, this code should work
Otherwise I'd say copy
into a bookmarklet on your bookmark toolbar in chrome or whatever browser you use, click on that bookmark, and the game shouldn't scroll at all just using the keyboard.
