Thanks for the feedback! I'd be interested to know your specs. This is quite demanding game and though it started with MV, I'm now using MZ. There's some optimization coming with the next update and I'll try to find more ways to improve the performance along the way. But there's one problem: I'm stuck with a certain version of the MZ3D (v8.3) because newer versions will cause bugs for this project that I haven't been able to fix. Same goes with nwjs (I can't update it beyond 0.5x), but that is probably because of some plugin incompatibility that I have to dig deeper into at some point.
But I'm glad to hear that you like it so far!
