Super fun so far, but as stated, there are a lot of bugs to work through.
Trainer battles will start, but our character will never show up and the battle never actually begins. You just get stuck in the pre-battle animations, staring at the opposing trainer. Reset is required to fix.
This one seemed oddly specific, but when catching a Lotad (and ONLY Lotad) in the first area, the very next encounter has no Pokemon and you get locked in the battle screen with no options. You must soft reset to fix. And then after resetting, if catching another Lotad, the same issue happens. I haven't had this bug occur outside of catching a Lotad in the first area.
When buying items, sometimes the quantities you buy are not correctly added to inventory, but the full price is deducted from your funds.
A beneficial bug-- if you have a status condition (poison, paralysis, etc), save the game and reload your save, the status condition will be wiped away. :)
Not a bug, but the encounter rates need to be dialed down. I'm getting locked into back-to-back-to-back battles in grassy areas, and sometimes it's very frustrating to just try and walk. Even turning down the frequency by about 20% would help immensely.
That's what I've found so far after only about 30 minutes of actual playtime. This game has a ton of promise, and aesthetically, it's one of my favorite Pokemon experiences yet.
Also, give an option for windowed mode, please. :)
