The Boss battles MVP is done!
This one was pretty hard (took a long time to debug), because the tile system is really designed to house 1 unit per tile, so tons of extra logic was needed to ensure a 2x2 unit didn't break everything. I had to make some concessions, like blacklisting certain abilities for and against bosses, but overall the experience is very cool.
Right now there are 3 boss teams I've built, which are all thematic as you can see below (they have "flankers" that fit the boss). The practice mode will allow you to select a boss to play with, while in Endless mode they'll show up every 5th floor.
They have higher stats, more abilities than regular units, get multipliers based on floor level, and have a small chance of "mutating" (that's the pink/purple hue) and being even stronger.

Next up, a music player (that should take 30 minutes) and then a biggie: items.
