Hey, I'm glad you liked it, and I appreciate everything nice you have to say about it! I put a lot of work into this game and I'm still developing it, hoping to make it the best it can be.
Indeed, there are a lot of stock RPGMaker assets, but I did want to spice things up just a little with some custom sprites, the shifted camera, and some other tweaks. Looks like it worked!
I'm glad someone said something about the casino manager comments, aha!
I've never actually played Undertale, interestingly. I know it has funny writing, though.
You can actually play the latest version, for free, in the browser! The Jane portraits have been totally overhauled (and they get larger), and there are some more rooms!
