Thanks for checking it out!
Hm. The web version is the same as the download version, so each level should have a door to descend into the next level. Maybe I misunderstand the problem though. I think what you mean with the “skull looking gate thing” is the initial spawn point where you are resurrected. Holding down space for auto-walk should eventually lead you to a door, maybe the pathfinding got stuck and you have to walk away from the spawn point a bit :D
I can definitely see your point about the first-person style! I specifically choose it because I felt just doing another top-down 2d roguelike game wouldn’t be fun for me, but that’s totally subjective :)
EDIT: I just updated the beta build to include a simple 2D mode for a more classical roguelike experience. You can enable it in the settings. Additionally the pathfinding should now go around the spawn to avoid any confusions
