Cool - playing this made me want to try making a simple RTS some day :)
- Cool if you did this all by yourself in the time limit. I suppose the main lesson is the classic issue of scope, and trying to figure out you could have prioritised over other things to have a more complete game quicker. - For example, if I were you I wouldn't have bothered spending the time animating your character until you had the core design more functional. I think it would have been fine if they just floated around, and remember that you're designing everything, so you can do sneaky things like simply make your characters floaty ghost style things that don't require animating ;) - More broadly, the visuals are nice but you could have gotten away with simpler, quicker stuff to give you more time on the game itself.
Still though, I don't want this to sound negative - it's cool and I bet it was interesting to work on :)
