It's using a monospace font instead of the proportional version of Verdana (the normal default font in Caliross). As you can tell that's not normal.
Some basic troubleshooting questions:
What specific version of Windows do you have?
(I'm guessing Windows 10 something from the window frame in your screenshot. Right-click the Start button and pick System from the menu. Here it should say something like Windows 10 ???, Version xxHx, OS build xxxxx.xxxx.)
What language is Windows using?
(In Windows 10 this is at Start, Settings, Time & Language, Language, Windows Display Language.)
What scaling is Windows using? (A percentage.)
(In Windows 10 this is at Start; Settings; System; Display; Scale and layout - Change the size of text, apps, and other items.)
Things you could try:
Right-click Caliross' "Game.exe", pick Troubleshoot Compatibility, and see what Windows thinks.
If your system scaling isn't 100%, try setting it to 100% temporarily and running the game. (This might require a restart and might make the OS stuff hard to read until you set it back.)
If your system language isn't English, you could try using the program

to run it in "English (United States)". (You'll have to add it to the context menu or application profile by right-clicking "Game.exe" and going into the Locale Emulator submenu after you have Locale Emulator installed.)
Update Windows until there's nothing left but Optional updates, then update your video drivers from NVidia, AMD, or Intel. You never know.
Good luck!
