This is a pretty great experience.
The ability to loot your previous character is really clever. That did make for a few frustrating times when the character was in the middle of some spikes so you had to take damage to loot, but it was still manageable.
It has re-playability because of the non-linear layout. I completed the dungeon and found 0 out of the 7 relics. No idea how big the levels are but they seemed quite large and I don't know how much I was missing. An exploration % would have been neat but there was the gold and relic count that I would imagine gives an approximate percentage.
I did feel like I was fighting the controls every once in a while when attempting long jumps. My expected launch point for the start of the jump was different than what it actually was so I often came up short. The double pit (where the second pit opens up underneath after you walk on it) I must have attempted 8 times. The level design was thought out well enough to be able to loot the body without having to take much damage.
The gravity and levitation wand were interesting. I couldn't find a place to use them to access anything I couldn't without them but I didn't try that much as it was close to the end of that level.
No idea if the vending machine was functional. I couldn't make it accept gold and hitting it with a sword didn't do anything.
I hope the neon lights and general campy humor gets increased in later levels. I did want more interactions (and maybe they were there I just didn't interact?).
All in all a really interesting game that I think will do very well :)
