You can use this handy-dandy guide on how to disable DPI Scaling that I just made:
1. Press Windows Key+R. The run dialog box will appear.
32 Bit
2a. Type in "C:\Program Files\Steam\steamapps"
64 Bit
2b. Type in "C:\Program Files (x86)\Steam\steamapps"
3. Click 'OK' or press enter. The run dialog will disappear and the File Explorer will open up.
4. Open the folder titled 'Blockland'.
5. Right click on 'Blockland.exe'. If you do not have file extension viewing enabled, then it will just be titled 'Blockland'.
6. When the right click menu pops up, click on 'Properties'
7. A window displaying the file's properties will pop up. If it doesn't appear, wait for a moment.
8. In this file properties window, click on the 'Compatability' tab.
9. Enable the 'Disable display scaling on high DPI settings' checkbox.
10. Click on Apply, and then click on OK. You can now run Blockland.
