by the way, it impossible to play trough site since the game will be smaller and u won't see hints or enemy hearts.
i see, interesting idea, but an exclamation point might a bit too obvious
There's already some kind of hint for that, actually, but it's not really obvious. The enemy stops bleeding around a second before they're back to a normal state.
I think the solution would be to either tell the player about that beforehand or make them stop bleeding earlier.
