Hello,
Last weekend I streamed your game. Overall, I actually really enjoyed the game, it was really well put together, but it's not without some flaws.
The mapping itself looks really nice in the "new version". The writing is good, and I enjoy this meta narrative. Actually, the reason this peaked my interest is that my own game that I have been working on has a somewhat similar story concept to this, so it was interesting to see how someone else explored this idea.
There are some flaws though; my record with puzzle games is pretty poor, I guess I am too much of a smooth brain sometimes, but I do genuinely feel that the game starts asking a lot out of it's players before giving them a chance to come to grips with the core puzzle element.
After transferring back to the new version of the world for the first time, I started getting weird frame timing problems, and then those frame times ballooned into poor frame rates. It seems the game could do with an optimization pass. (In the stream I didn't remove the technical point from your game's grade for this error, however, I have since changed that and removed the point from the game's technical score)
And finally, the game could really use configurable controls. I understand RPG Maker's archaic persistence to use arrow keys, but some players prefer to use WASD and being able to provide the option so users can decide which control scheme they prefer would go a long way. I believe you are using MZ. I don't know what the equivalent plugin would be for MZ, but likely it's available for free from Visustella since Yanfly's Keyboard Config is a free plugin for MV.
I hope that you expand on this concept in the future, I would be interested to see what else you make!
