Godot is brilliantly simple, isn't it?

Thanks for the feedback. The bar thing(even bars for unit health) was something I was considering, but due to 'Real life' issues, I ended up having to make most of the game in the last 4-5 days. So I had to leave that out, which I regret. Will be implemented in the next patch, maybe with some story too.

As for the wake up issue, do you mean when she's fully awake? There are currently 3 states: Asleep, Groggy and Awake. You can wake her from Groggy to Awake, but waking while Awake should have no effect.

Actually, there was a 4th state that I didn't fully implement. When awoken while Awake, she turns Annoyed. This makes her so that she won't respond to your commands 70% of the time, but uses very less mana for any summons. But I chose to disable this till I either tweak it or remove it completely.

Pro tips: There's some text to the right of the board telling how long you have until the wave ends or begins.  Get her fully awake at the 2nd or 3rd turn of a wave, but try to time her sleep to occur right as the wave ends. Also, use a combination of the knights and 1 - 2 turrets, unless you have lots of mana. The knights are there to stop enemy advance, while the turrets pick them off.

It is, actually, fully turn based. After you press wake, she takes 3 in game turns to become Groggy. If you wake her while she's Groggy, she takes 2 turns to fully awaken. If you leave her alone, she goes back to Groggy, and then to Asleep, in 5 turns each.

But I guess I need to indicate it all better in-game.

Thanks for the feedback, though. Much appreciated!
