Thanks for the feedback! I'm using the Dawnbringer32 palette, so between the grass and the goblins there's not many more greens to go around. I'll try adding some shadows to make them stand out from the grass a little more.
The timer at the top of the screen determines how long it takes until enemy units get an attack order. If an enemy hasn't come near a knight and doesn't have an attack order yet, it'll stand around until one of those two things happen. I'll be tweaking it in future updates. Controller support is also on my to-do list, which I think will help a bit.
Glad you enjoyed it!
