Just a quick update.
I began a new adventure with the quickstart party. This time the party had an easier time with the caterpillars. Their vitality must have been low previously. I read somewhere that can prevent hits from penetrating armor. My spell-casters were also able to land a few spells, whereas previously they missed every time. I was able to locate an underground are, and the visuals actually looked pretty good down there! Ultimately, a group of "?HUMMINGBIRDS?" wiped the party before anyone leveled up.
This second run improved my impression somewhat. The UI is clunky, but I could get used to that. The graphics and feel are authentically retro, which is good. This first area has enough non-combat interactions to make me curious what else is in store, and the NPC dialog made me smile. Combat feels either too slow or, if I hold [enter], too fast. This issue with combat may be a non-starter, though I should see how it works after gaining a few levels. Lastly, the mechanic where I don't even know the name of the enemy I'm fighting is neat.
I purchased Legends of Amberland on the same night, and they are practically mirrors of each other. Amberland runs beautifully in 4k, has a UI that becomes 2nd nature after 30 minutes, and the party just breezes through combat. On the other hand, its world feels like an assortment of quirky side-quests rather than an promising an interesting plot. I'm basically fighting enemies for levels and gear only so I can fight stronger enemies.
