Good enough for a first game! It's cute and the stage's appearence looks well researched. Love this style!
Just the idea of exploring and navigating the Underworld's mazy and uneven terrain is pretty inspiring.
I'll say it again, the style is cute, and I can see lots of care's brought to the stage's presentation! Love it!
Welcome to the Jam.
Note: Whenever Tenshi jumps, it feels floaty, committal, and slow almost to a fault, due to not having control over the jump height and having low gravity. It's fine in this game here since there's no sense of urgency, but that is something to have in mind if you'll be making other platformers.
