thanks for releasing the demo, I hope it boosts your KS to reach the goal.
I've played for a bit, here are some impressions.
The game started out with showing the input keys, however, I use a German keyboard, so my "Z" key is not very close to the others. I therefore decided to plugin a controller and it worked right away (no need for restart) which is nice.
The game then took very few seconds to generate the world each time i died, I think the wait time is a-ok.
The game itself has a cool look, I think it's very coherent and the impact and sound of different actions is great.
It's interesting to see dynamic lighting on the characters (did you implement that yourself or did you use stuff like Sprite Lamp? (http://www.snakehillgames.com/spritelamp/)) But I think the effect is a bit too exaggerated, for example in the picture above my character looks almost like a mural made out of stone. I think the gradients on the character's face should be a bit softer, but that's "whatever".
The game itself was fun because discovering chests etc. all the time was motivating, but the combat felt really uninteresting so far (and I've played around 20 minutes). I think making easy enemies is ok, but they genuinely only were a thread when the world was built in an unfair way (for example a drop down to a chest with a plant on top of it). After the first few guys I would have expected some more challenging encounters already, but the birds fell flat in that regard.
The UI is really cool, the map in the top right etc. is really well done.
So yeah, for my taste stuff like Rogue Legacy or demon peaks (also made on monogame, https://demonpeak.itch.io/demonpeak) is much more interesting, even though they are not necessarily comparable since they are mostly melee.
