Hey, thanks for playing! There should be sound, but it was added very recently, about 20 minutes ago. Maybe you played before then? (Might need to refresh the page before trying again if it's cached)
The camera system is a work in progress, it tracks down when falling, up when jumping, and eventually levels off when still. I may need to re-think that. Thanks for the feedback, very helpful! Maybe I should make it based off the mouse positioning or something like that...
One more note, there are 8 possible endings, only 2 are available all the way at the very end. Most are located on interactions throughout the map, and two of those are effected by how much Mana you have. (You attempted the hardest one, need full Mana) There is one more "secret" ending for accomplishing something on the map. That's all I'll say for now, hehe.
