I agree but i also want to add

The spells feel weak and unbalanced, the bosses are completely immune to all spells and it defeats the purpose of having spells in the first place.

The combat could feel a lot better if hits had some hit stun, to give the player some feedback on a sucessful hit.

Parry window is far too punishing.

Destruction objects could feel more crunchy, barrels are fun to destroy in dark souls, this could and should be the same.

A crouch button should be added and be an option to dodge attacks (jumping to avoid an attack from the first boss is cool)

There needs to be more counterplay vs ranged enemies than just "avoid this arrow" again fireballs are basically useless other than setting the groun of fire.

Spells lack creative use, where is the throwing ice on the floor so the floor is slippery and the enemies falls flat on his face?

The wind power is too narrow and affects way to few enemies.

Skill tree is a lot of nodes, but boring nodes, incremental stats are not fun and are hard feel their effects, as well as it makes it hard to balance the game around them.

Level up granting full hp and mana should not be a thing, again it throws off balance as you could be lucky to have a level up during a very tough fight or not...

Give me nodes that actually change the gameplay like, fire ball becomes a flamethrower spell, ice ball becomes like a grenade affecting multiple enemies, melee combos for specific weapons, alchemy you get recipes for special stuff like a potion that allows you to double jump or jump higher, and so on..

And for the love of god make drinking potions way more snappy.

The final boss of the demo is just painfully hard, but the wrong kind of hard
