This game would benefit greatly from a tutorial. The timer felt a little too short to actually accomplish anything for the first few times resource gathering.
Really fun gameplay, great visuals and audio. Only issue I had was that there was little to no info given during the game, if there is an objective then there is no indication as to progress.
The concept is cool, my main gripe is the lack of telegraphing, you have no idea how much damage you are doing, how many waves of enemies are left, how much time is left on the timed levels or how much health the enemies have left. I would also recommend having a prompt in game when you start along the lines of "Press enter to skip dialogue".
