Seems like a cool concept and very well-made, but needed more explanation to get the player on board.

Can't stop looking for the heart!

Informations about controls would be helpful. I just figured out the movement and the dash. Did their even spawn hearts? I ran through the whole dungeon 2-3 times during a run but could not find it.

The concept and idea are pretty interesting, though I am not sure if the heart is spawning properly or if there are some conditions. Also as others mentioned, controls would be nice as it took me quite some time to figure them out and I still do not know if you can "reload" your fireballs.

Otherwise good job, it's qute enjoyable.

I like the concept of having time as your health, too. But I wasn't able to find the heart D:

(Also I just learned from another comment here that there's an attack and dodge. Adding controls either in-game or on the project page would help a lot)

please add controls to the page! it took me until my third run
 to figure out that you can shoot fireballs, and on my fourth i discovered the dodge recharges them.

also, i couldn't find the heart. i checked every part of the map and didn't see it. do i need to kill enemies to find it?

aside from confusion on controls and objective, i like the idea!

i actually had a similar one initially, but instead of time being health, time was mana. (though i ultimately scrapped that idea)

nonetheless, i like the idea- though would like a bit more of an explanation as to what i'm doing and how to do it.
