I'm amazed how much you made in a ten day period!
It took a while for me to really catch on to the mechanics, even though I read the instructions (a few times.) And it also took me a while to actually become efficient in collecting resources, once I really understood what I was doing.
I wish that I had more time to invest in the game, I didn't get very far at all in the grand scheme of things, or so it feels. I was only managing about 150 resources at my peak, and that wasn't nearly enough to make progress in defending the Time Portal.
I can't nitpick anything, I know this must have taken a monumental effort to put together in such a short time frame. Except! I wish that they upgrades weren't randomized, I wanted to take double jump the first time I saw it, but couldn't afford it. Then it didn't appear when I could, then it did appear but I didn't see it before choosing another upgrade because it was in a different position in the upgrade grid. (I did get it eventually!)
Aside from that, I think the music could be more prominent. But that's really all I can say. I'd love to see what comes of this, if you decide to develop it further!
