I'm happy to hear
I get what you mean when it comes to the horizontal/vertical locking, and I think it would be useful.
When it comes to the font, I do agree that it's not the easiest to read. I can't draw the font on a smaller scale than the pixels of the game unless I change how a lot of things work, but I have been looking at changing the font so that it's more readable at least.
I have been working on making the game a lot more polished and convenient to play for the next update, so a lot of these things should be fixed.
