Spoilers for the demo
Amazing demo! Solo development projects often have a least a few glitches glitches at this stage of development, but to my surprise I did not experience a single glitch during my 50 minutes of play time. Can tell you've really worked hard to get a solid foundation of the game. The animations and the feel of the game in general are great! Love the level design as well, would like to see more chances for vertical combat with special bonuses to plunging attack damage. The final boss was great, tons of moves and enjoyed figuring out how to deal damage to him. Once I figured out the trick though, the fight became less interesting. Maybe make a second phase where he counteracts jump attacks to his head in someway. As he currently stands, he is too easy (in my opinion) once you figure out how to deal damage. Sprinting was very useful in the fight, maybe make it consume stamina. Also, I was not aware sprinting was in the game until the very end. Maybe I missed a tutorial pop up, but it would've been good to know. I'm now realizing that's how you get that secret chest in the water cave. Love the secrets by the way. Tons of secrets that you can hide when there is so much potential for verticality in your game. Great job, would love to see this as a full fledged release.
