What I like about this game and the other one is that they're actual RPGs in RPG Maker that are enjoyable to play with enough testing and QOL improvements for the gameplay. The nice visual update in this one's pretty cool too.
I had something similar when I entered and left The Boundary for the 2nd time in 0.05, completely black screen without any text or bars. Didn't happen again in 0.06 for me yet.
