Game looks fantastic so had to give it a go, will list bugs as I go along to help you troubleshoot: 1# was at the very start where for me it showed 'whats yer name lad!' behind all the other text while the ship is crashing - 2# is walking right into wild grass always causing an encounter.
5# - small hills that we shouldn't be able to walk over, I walked right over it but then turned around to try and go the other way instead - coming back now I can't walk over it so i'm sure we're not supposed to be able to - however I am now stuck with making progress as walking into wild grass from the right always causes an encounter (without steps being taken forward)
Overall - few small glitches here and there that just need to be patched but the game looks really good and I really like the fighting animations - also never played a pokemon game that felt so smooth (accidentally forgot favourable moves when leveling up due to fast input times) - I enjoyed playing for now!
