Hi,
I really enjoyed the demo first of all. It gave me a good couple of "Aha!" moments in the time that I played with the platforming mechanics and the level design in how it flowed together. My only concern was that if, as an avid gamer who plays a variety of games, the platforming required to unlock the bridge was difficult for me, then I can only imagine someone who is more intermediate in game experience really getting frustrated with it. So if you could tone that down just a tad bit for other players upon release, that would make the game, I'm sure, a little more accessible if it's your intention to hit the intermediate-to-hardcore gamer audience range.
Also, is there a point to crafting another sword after receiving the one that is from the old man earlier in the game? I may have missed it, but I wasn't able to find a recipe for the great sword blade and therefore unable to craft the great sword to test out the differences in weapons. And then to pair that with the end of the demo which tells you the sword you got from that old man is super important, I felt the great sword was a missed opportunity to demonstrate more of the combat system while hiding the special abilities the Graile is supposed to grant the player. Very small nitpick though.
Overall 10/10 demo and would love to purchase this game on release! I am going to continue to tune into your YouTube videos and Twitch streams. Cheers!
