i have complete solasta and it was fun and very estetic but i wish i could play in the dungeon maker with my character after i'm making a dungeon in the dungeon maker and not to start over with new character at level 1th also on top of that if i making a dungeon mybe to make co-op / multplayer

about the dungeon maker, i wish i could put creature on a floating platform or any dynamic like that

A lot of us, have extensive wish lists for the Dungeon Maker. How much of them will ever materialize, remains to be seem.

I want a option to elect a party leader to speak for everyone, or at least put reasonable options. Having my Lawful Good paladin say chaotic evil shit like "kill everyone or wheres my gold" is wrong and break the conversation for me.

the thing that made me not playing further... a paladin who talks about donkey piss beer... just one of the dialog fails in combination with classes, races, good or evil... kind of a bummer

For sure! A paladin wouldn't dare say that. It's a very ambitious game nonetheless, and I admire that. Hoping to see patches in the future.

I don't even like this character background system with its severely limited choices. But if I hear now that it doesn't even really affect the dialogs, then I must consider it a complete waste of time.

Speaking of Waste of Time. do I really have to play the whole "donkey piss" scene including these boring tutorial levels every time I start a campaign? Or is there a hidden shortcut I haven't found yet?

Yes there is a switch, see the attached screenshot....

Paladins can make jokes and arn't wooden. 5e Paladins arn't all the same stone cut outs that come from previous editions also Gary G. himself said Paladins kill traitors and such willingly as LG.
