Okay so I made it to level four, and continued on my way, and then when i got enough xp to hit level 5 it says "max level reached". You need to increase the level cap, There is no reason for me to continue to play if I am going to be wasting my XP. I do not even think I have finished act 1, which was supposed to be the full content of the early releases, why would you arbitrarily limit level to four?
Also some of the costs of equipment is too high, I should be able to buy boots and a helmet for my guys to look super cool for less than 1200 gold.
Good news. You won't get to keep your character, so all your XP is wasted. The limit isn't "arbitrary", DnD has a power curve where every 5 levels you get a massive boost. So 1-4 is a "low" sort of power level. I suspect by release the xp curve will be different, and you might not reach lvl4 quite as soon.
As for price of gear: The cost is reasonable, the gear has powerful effects which shouldn't be handed out willy nilly.
Act 2 and beyond be accessible in early access. It's as simple as that.
It might be later, but right now the game isn't finished. And I doubt we'll get the full game until the official release. This is game testing to get the mechanics of the game great. You don't really need to have more levels or lots of content to figure out if "cunning actions for everyone" is a bad idea. (It is Larian, it is).
Once they have nailed the design ideas, and also polished bugs etc, then the game is ready to ship.
