Hello there. That's an issue that can sometimes happen with pixel fonts and that can be fixed with proper settings. Font aren't made with actual pixel, but with vector, interpreted as pixel with the right scale.
For exemple, in photoshop the 1:1 scale correspond to 17pt, without anti-aliasing or the font will look blurry. Check if the kerning is set to Metric and the tracking to 0 or the spacings won't looks right.
If you want to use the font at different scales always pick a multiple of the base size. At X2 it should technically be 33 but depending of the software it might look better at 32 or 34. In my case it looks perfectly fine at 17, 33 and 50 pt in photoshop with the previous settings.
Using pixel fonts in a game engine can be tricky. Some game dev prefer to use sprites as they're already perfectly sized. My trick with GameMakerStudio is to set the font at the double of it size and render it at the half.
I hope it will help you acquire a better result with the font.
