Interesting game, i like this colorful mushroom theme and the character. You had time to create and implement all these voice acting as well in time. This is more like tower defending than and regular rts-game, because the enemies coming in regular waves and you have to more manage your settlement than to react things very fast. I like how there are many different variations of interesting mushroom buildings to player needs. You have more things added here than i though there would be time enough to get implement to rts type of game.
Edit: moving map with keyboard keys and having a minimap would be great. Also having a standard grid-based building would be fun, maybe with some solid walls too! This is enjoyable and fun game indeed.
