The alien characters are fun looking.
I find the controls a bit too awkward and not well explained. Having the playable characters have unlimited range of movement is also an interesting choice in strategy games like this. But that makes me wonder what's the rules governing the aliens' movements so that I can plan around it?
On that note in my game it became soft-locked after the alien tried to move into an already occupied slot, but couldn't complete his turn.
Overall, interesting idea and I would like to see the controls and UI improved further.
