I gotta say, this is a pretty neat demo! Cyberpunk has always been one of favorite genres so games like these are right up my alley. However with that being said, I did notice a couple areas that could use some improvement. Haven't reached the prison yet so I can't comment on that yet. I'm currently going through the side quests atm.
1. First off combat is a little too dependent on consumable items atm, and one way I can think of to alleviate this issue is lowering the ST cost of the party's skills. The costs are really steep and take up the majority of a party member's ST bar to even use one of them. This leads to item hoarding, which can be a big issue for RPGS. Being able to use Cecilia's heal more often would be a great help because it wouldn't make me feel like I have to hoard my Syringes and Crystal Water as much for upcoming encounters. Quite a few enemies in this demo have AoE and multi hit attacks so a change like this shouldn't make the game feel too easy. It would also liven up combat by reducing the need to spam basic attacks to deal damage due to low ST. There were times where I wanted to use Zeno's or Himari's offensive skills but couldn't because of the cost.
2. Another thing I noticed is that Phoebe's boss fight (the one from Luna's side quest) is incredibly punishing and it's mainly due to the debuffs she's constantly spamming on your party. if she isn't locking you out of your abilities with her AoE "Get Hacked!" skill, she's making the party take themselves out with "Like What You See?" ,which is also AoE. Basically, I would remove the hack debuff with tablets only to have her reapply it the next turn or use her other AoE skill to make the party attack themselves when I tried to heal. It would basically be like that on repeat until I lost.
