Post-jam update

Hello, everyone! It was my first LD Compo and my first try into RTS games. So, what I've made on this game jam was really raw and unpolished. Now I made many improvements into my game to make it more fun to play.

# Changelog:

+ Controls update. Move your camera with arrows, speed up with Shift key and jump to your selected unit with Space.

+ UI update!

+ Multiple unit selection! You can try it with holding your shift key or with new unit box selection (just hold your LMB and draw a rectangle around them)

+ Advanced unit control - Attack, Move, Hold position and Stop orders are available via UI buttons. Also, with hotkeys ('A', 'M', 'H' and 'S' respectively)

+ Medical building, which heals your dwarves around it.

+ Population limit mechanic instead of increasing cost of dwarves. Build additional power plants to increase your unit limit. Now it should be easier to play.

+ And many more minor improvements...

There are still some pathfinding issues, no tutorial, and more things to fix. Also, I have huge plans how to improve this game, so stay tuned and check my itch.io page from time to time, if you are interested!

P.S. 'Play' button on WebGL build is still not working in non-fullscreen mode.
