Thanks for playing, and for your feedback!
Yeah, in the next version, I'll include the shortcuts for ending a turn, since it was wished for by many other players who commented here - unfortunately, I'm not allowed to update my game it until the jam is over. But in the next version, this problem will be solved.
The attack ranges of the enemies are highlighted right now (if you mouse over an enemy, you can see its possible attack fields highlighted in orange) - for a future version, I'll make this more obvious. (Maybe I'll include it in the tutorial somehow, to show players how they can see which moves the enemy can make.) I'm also currently working on some animations for moving, attacking, taking damage and dying - unfortunately, there was not enough time during the jam, but I'll include it in the next version :-)
