Well, I've played for a while now, so I'll catalogue all my issues here for you to look over.
BUGS:
1. for some reason every time you do the squatting minigame the camera will zoom out a little more until it is eventually under the floor, at which point when you try to do squats the minigame will break and the game will lock up forcing you to restart.
2. mimics can attempt to start combat with you while you are loading into another combat encounter which leads to the game crashing.
3. had a problem every now and then with saving in town crashing the game with an error popping up about jumping or something, I'll try to grab the info if it happens again.
4. had another crash when I tried to start combat with a worker in the overworld where the game tried to reference some NO_NAME and couldn't find it. Only ever had it happen once.
5. there's an issue with the dungeon spawning of the final dungeon which can produce fully walled off passageways, I had my way to the entrance to floor 5 blocked unfortunately.
6. slime halves your stat bonuses if you gain any stats while it's on you, meanwhile acid does not seem to halve stats like it states in the status description.
ISSUES: mostly just balance stuff
1. size is probably the most important combat stat simply because of range issues. This is fine mostly, but when you're too big it becomes hard to pathfind and see things on the ground yet you need to stay that height because getting into a fight with a bigbarian or some other height scaling enemy would lead to an incredibly awful fight. I want to ask for a reversion to base height scaling or a separate combat height scaling option.
2. some weapons are incredibly overpowered. Shields, especially the stone shield give too much shield and AP while shielding nearby allies too and costing no AP, completely invalidates concentration while making you pretty much invulnerable. The meteor staff has a gigantic AOE explosion that knocks back, knocks down, and exponentially scales chest stat and thus it's own damage until you use something else. There are some others but I'd say these are the most standout picks for me.
3. size sword is problematic on enemies. I wouldn't say it's particularly overpowered on the PC, but against a group of bigbarians I see no way to survive but to spam the overpowered shields. There's no way to escape their full-map strikes and if they're significantly bigger than you then you have to attack from range, grow bigger yourself, or close the distance while taking huge damage. Considering defense is hard to come by it makes the size sword bigbarians suck to fight without a shield.
4. stun, just stun. It either stops you from doing nearly everything or is a minor inconvenience as you guard with your shield and continue to fight without moving because your shield gave you AP and shield and let you attack again. It can also practically end a fight in one move when you use it yourself. I'd recommend limiting stun from stacking at all or even just removing it.
That's about all for now, there's more I could comment on but I feel like I'd get a bit nitpicky at that point. Regardless the game is much better than I initially gave it credit for on first look. Keep up the good work. It should be noted that I'm on ver 6.7 but I didn't see any changes regarding these things in the 6.8 patch notes.
