@mergan I've heard of it and I know that MonoGame has an extension for it, but I prefer something that it optimized for my game and not something generic. Plus, I already have been working on this game for over a year and I already had a level format for it already (I've been painfully hand-writing XML files for the longest time).

And I just find writing games including the level formats, physics, AI, etc "from scratch" much more rewarding. Otherwise, I would be using a full engine like Godot or Unity.
