I think if you had a tutorial, it would help a lot. I didn't quite understand what I was supposed to do, but it looks like there was a lot of stuff to discover, so well done on managing to pull this off in three weeks!

I am not good at all in these games, I kind of lost... everytime I played! But it's quite impressive to have built this in 3 weeks. We can collect resouces (wood etc), build things, use inventory items... in order to survive to waves of enemies. The graphics are simple but ok, and the gameplay seems to be exactly what to expect in that kind of game. Good job!
