Thank you!
The "hardware" part actually happened almost by accident, I first intended the game to be played by keyboard only. But I want my games to be playable on phones and not just on PCs (and I had no idea how uncommon that was in this jam), and while I quickly found a way to display the phone's built-in telephone keyboard, it came with some challenges I couldn't quite solve (like how those keyboards have different layouts on Android and iOS, and how you have to enter a submenu (at least on Android) to select the * and # symbols), so in the end it was just easier to build my own keyboard instead. And I first intended to hide it in desktop view and only show it on phones, so that desktop view could show the display in full screen, but when I started scaling up the display, I realized that for a game almost only containing text - and in a quite large font, too - anything larger than 420 x 240 pixels felt way too large. So in the end I just kept the keypad in in both views.
Let me know if you need a walkthrough or something!
