Seems skill2.ogg_ is missing in the current version, that is causing a bit of a softlock. (I did go and download version v0.5 and get the sound audio from there and simply put it in the current version. Which did fix the issue.) Great work though, you have a fun game here so far, and hope to see more of your art.
Thanks so much for your comment! That makes me very happy!! I hope to finish this game soon, and I'm also working on another similar but shorter project <3.
Also thanks for telling me about that bug! It must be a problem when exporting without the default RPG Maker assets.
I'll work on how to fix it.
