Oh man this is so complex my brain is actually brain not :"D Reminds me a lot of Advance Wars/Wargroove.
I'm actually enjoying it though! In the beginning it took me a bit to understand the mechanics properly, but once I got the gist it's pretty easy to go. The UI is really tidy and I love the sound effects. The dice is giving me a lot of joy whenever I click on them.
This is very good and I might give it more play later. So far I think the only dice that's almost useless to upgrade is the one with lightning? I might have missed something, but everything else have other use other than for unit launch.
Big props to you for this making a game this complex under the jam, really.
