So after play though about twice, I have some good and bad to say. Since it version 0.2 I will give some leeway, but I find honesty is the best way to improve your works
The good: I like the sprites and creative typing of some of the new lustermon, besides the ralts line, the starters have types and stats that I would not think to put on them and I want to see more in the future. From digging around in the files to see which ones I missed, I am surprised at the choices and intrigued you didn't just go for the easy ones to make into waifus.
Game seem pretty balanced so far, not braindead easy but not annoyingly hard.
The bad: While the world is large, it feels kinda barren. Maybe drop another item/trainer or two to make the wild areas more worth exploring.
The stairs on the left of the pokecenter makes sense, but you can just walk off the "cliff" on the right hand. If you add a stair sprites is would at least make it constant that there is two floors.
Also there is a slight grammer mistake with the defeat quote for the trainer just outside the RV (The one with the stuffle Lustermon) just a double capitalization, minor mistake.
Just my nitpick: I will complain about the first battle with L.Eevee having sand-attack AND a potion was kinda annoying. Getting her almost dead only to have her heal and trying to work with ~66% accuracy was a not that fun. To clarify, I just have a problem that its the FIRST battle, when we only have one mon, so we can't swap out to get rid of the accuracy debuffs AND she can heal. Rematches onward is fair game.
Also any Lustermon with cute charm is kinda boned, since all mons are female. I would recommend giving them a different ability.
