Hello! Some good news is that for some reason this version was able to download itself on my PC correctly so I could play it. The bad news is that I think it's buggy at being slower than it should be as it was waaay to slow to move the characters. I tried your online version again and the speed is much faster, but I'm still the type of guy who likes to be able to dash in the game I don't know if others feel the same way but that's my first feedback.
Unfortunately my save file keeps getting lost on the online version, but I'm going to try the online version a second time soon and see how far I can get in it. I've only seen the introduction so far, but basically everything is very likeable and enjoyable. You have a good and interesting story from the start and it's fun to interact with objects and get things, I liked the spirit doll battle thing and the skillsets and how you can explore different places.
I don't know if they're optional or not, but it feels that way and is very fun. Mapping is excellent too.
The game is otherwise very beautifully presented and I like the choice of music
Unfortunate that's all the feedback I can give for now, but if I get somewhere with the online version I'll let you know. Good luck with what you add and do next with RPG Maker!
