Really good game! 1068 seconds here.
It looks very polished, nice UI and sprites and the concept is really interesting!
I had 2 minor bugs, once I could play an already dead char (the aliens refused to accept Vasquez carcass as an offering) and always after all chars were moved, it seems to select the last one played, regardless of who I clicked. (Maybe that's also how I could play dead Vasquez). These were small bugs though, never had a problem because of them.
It's a really cool concept, but I would have liked it to play faster! Because 10 seconds isn't that short and the badasses move quite slow on top. It would take forever to clear the map like this, while there isn't really anything new happening. (Of course, it's a jam game)
I could see this work super well if it was a bit more like a tower defence with different levels. Instead of slowly going through the map, have a limited area where enemies will come at you constantly. They could also destroy some of the obstacles so you actually have to move - then it's all about positioning. I think this could be a game I'd pay for! :)
Anyways, for this short amount of time this is super solid. See the suggestions as absolutely positive, because I already liked it so much. Well done! :D
