The widescreen is far too wide for the title screen's image size. First thing I noticed.
I liked the character art styles. The moving sprite, the chest and the faceset feels very inconsistently incongruent though. Especially when placed with the RTP tilesets and battlebacks. There's lack of sound effects/animation with the chest too which I presume is because of the one month time constraint.
The enemy battlers and the character styles feel very mismatched in some aspects. It honestly feels jarring to look at first impression wise.
There's textboxes that were cut in the weapons description.
...Welp that's the end of that.
All I can say is I'm sorry you had made a mistake of deploying with the unused files option. Do not rely on that. That may reduce your filesize but it tends to remove stuff that you need. Its often inconsistent especially with plugins involved.
