This is the batch of demo I got in the first floor of the disc. You WILL get a different one as they are all randomized upon first playing the hub game.
I am going to give my thoughts on these demos. Not exactly many, but what I compiled together while playing them.
(+): PS1 aesthetic well done.
(+): Gameplay is straightfoward.
(*): This game has mind-boggling effects.
(-): The crossbow makes fights too trivial in spite of low damage.
(-): Enemy AI is a tad simple. This made the crossbow even better.
(+): Highly atmospheric.
(+): You can pet doggy.
(+): Interesting premise, mechanics.
(-): Progression is quite a linear ride, aside from if you accidentally crash your ride.
(+): Drama seems interesting.
(+): Great pixel art work.
(*-): The demo sadly did not let me smoke more.
(-): Not related to the PS1 aesthetic at all. Fits better alongside surreal RPG Maker titles.
(+): Executes premise incredibly well.
(+): TWO well done aesthetics at the same time.
(+): Story hooks you and won't let you go n̲̩̲͈͈͗͊́͂ͅo͚͎̮̞̰̬̪͈̊͑̍́̔͌̀̿t͎͍̠̗̩̝͇̟̀̓̀̈́̓͆̌̚ u̜̳͎̘͍̜͎̗̔̔̇͑̄ͅn̲̰̥̟͙̩͍̱͖̍͐̾̾͒̂̃͒͌̋́l͙̬͓̝͇̯̐̄̅̔́̔̍͊ḭ͕̜̱̙͂̒̈́̒̎ͅk̰̞̱̤̥̙̽̄̀͆͗e̮̯̯̥̝̩͔͈̲͇̽̽́́ Y̗̯͙̬̓̓͆̉̿̄͂̒̏Ó̟̪̟̜͕̤͍͎̥̑̄͑̒̚ͅṶ̯͔̝̰͖̱̖͔̦̙̃̎̍́͆̏̒ͅ f̟̪̯͚̱͎̠͎̫̬̅͋̇̄́̊ṙ͚̣̫͎̀̔̓͑̽̌́̽ͅó̩̲̤̳̖͎͖̯͂̔̍̃͂̃̀̉ͅͅm̖̘̘͖̯̈̓̒́̌́̃͑ H͔̣͔̮̖̪̘̩͕̗̘͗͌̅̒͊E͚̤̮͓̍̓̍͒̐̀ͅŔ̬̫͈̰̙̘̣̥̬͉͕̗̿͌̈́̅̀
(*): Sorry! We could not find this blurb.
(-): Only slighty related to PS1 aesthetic.
(+): Good PS1 aesthetic and gags.
(*+): A few models look a tad highres here and there, but are well done.
(*): Peeb.
(*-): Late 2010's creepypasta-tier spooks. Though granted, this may be the point.
(-): Dithering is somewhat scaled incorrectly. Ergh.
(+): Cool PS1 aesthetic, neat.
(+): Nice music.
(-): Protagonist feels a tad floaty.
(-): And then SUDDELY TE STAR HAD VERY SPOOBY EYES!!!!!!!!!
(+): Great PS1 aesthetic. Amazing graphical work overall.
(+): Would replay.
(-): Dithering is scaled BOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOooo
(-): It is not clear how much you've wore down the monsters. Maybe swap their textures as they become more and more damaged.
(+): ...Sounds are ok?
(--): This game commits the capital sin of being a blocky downscaled mess. I would, rather bluntly, suggest to get rid of this facade entirely and be more honest. It looks bad and is the kind of thing internet smart-people chastise us for looking like.
NOTE: I will try to replay the game again to try to form a better opinion soon.
(+): Well executed PS1 aesthetic! Models look nice too.
(*): Heheheh text goes wobobobobobo
(-): Premise is barely played with much.
(--): Tank controls. Tank controls. TANK CONTROLS. TANK CONTROLS. TANK CONTROLS.
NOTE: I will also try to replay the game again to try to form a better opinion soon.
(++): Climbing mechanic is hands down amazing. Heh. Hands.
(+): Hooked on what'll be in the final game! Heh. Hook.
(-): 'Modern Retro' look not very appealing. Like if THIS MAN turned a N64 game into an UE4 demo but didn't bother getting new textures
