For a tech demo this was fantastic, much higher quality than most games and holds great potential.
The movement feels fluid and is easy to get the hang of and the shower scene was pretty good, though I wish it was a bit more interactive. Honestly, my only big gripe with this was the combat. It feels clunky due to the end lag of the attack string. Enemy attacks are telegraphed fairly well, however it doesn't feel like there is much you can do about it aside from jumping around/over them.
A dodge or parry mechanic might make a good addition, or maybe simply tweaking the attack string to have less end-lag on everything other than continuing the string.
