The game is quite broken in several different ways:
1) Sometimes you just don't get your starter. I had to use Beldum the entire run as my Mudkip was nowhere to be found.
2) Save before EVERY battle; you will need to soft reset often to get around potential when starting or in battles.
3) The level scaling is not great. One of the major fights against the Mercenary Yior, is MUCH higher level than other fights in the area with a level 40 Lucario.
4) Whiting out sometimes clears your team and refreshes back to the last save. Make sure you save often!
5) XP managment is tough in this as no matter how many pokemon are in the party, the amount of XP does not change i.e. if you were to get 1000XP and have 2 mons in the party it should be 500XP per mon. Instead, it is the same number distributed across all 6 mons in the party and does not increase or decrease when more or less mons are in the party.
6) This is niche and a bit nitpicky, however, playing on an ultra wide monitor (Odyssey G7) causes the UI to block important information like hitpoints in battle, pokemon on the summary page, and some box functions.
7) The Delibird Exchange is quite buggy when you have low money. It seems that you can go negative in the store but it will not allow you to close the shop after that.
8) The dialogue exchange between the Magma Grunts often gets stuck on screen after or in battles and take a while to be removed.
I understand that this is a demo, thus, I was expecting a lot of bugs. I want to express that I am very pleased with the experience. This game has the potential to be something BIG. At this time, I do not wish to continue playing until some of these items are fixed. I will wait until the youtubers catch on and post content on it before I return.
Best wishes to the development team! <3
