Adore the art, the music kick ass, a delight to play.
This seems like a fairly early demo, and I had a lot of trouble telling what was a fully implemented system and what was not. I'm not sure if filling the XP meter does anything for example?
I love the unique jump handling. It's committal, but with a small degree of freedom.
If I were to offer a significant piece of feedback, I think anything you can interact with by hitting down should be highlighted / have a prompt appear. It took me a while to figure out how to get in houses.
The game is BRUTAL! But I love it. I think you're going for La Mulana, and it blends that quality with early video game silliness wonderfully. Love the dialogue, love the art direction, love the animation and sound design.
I played for a while, exploring to the best of my ability. I pretty much only found spike balls and shurikens, a lot of seemingly dead ends, and the tank head boss fight guy. That boss whooped my ass for like 20 minutes straight but I did eventually beat him.
I might play more, I think I remember there being something I could afford with the upgraded wallet in the skeleton cave? And I never figured out how to survive the big drop into the acid pit below the knight either. I think the ultimate takeaway is that I was engaged enough to get that far, because your game is really hard.
