So in this devlog I added upgrades to my growing metroidvania, Lunar Journey. What is a metroidvania without upgrades? 

Nothing! So let me cover the way I added them. 

I made it so I can add a new upgrade in seconds. The process involved creating a scene with many exported properties which can change player properties when the player pays for it. 

One issue is that there is no currency so the upgrades cost nothing but that can be dealt with later.

Another problem is that I don't have time to make the art and ui of dosens of upgrades, so that will likely appear in a later update.
