Thank you so much, I'm glad you enjoyed it :)
You are right, it would have been cool to have a couple more enemies.
I think If I had the time I think I would have made it so the enemies were a lot more overwhelming and scaled in strength as the game goes on so you would actually have to put up a full scale defence against them.
I was a bit worried about making them oppressive when balancing though, because I saw a couple of people who really didn't do well against them on their first try, so I decided to err on the side of making them weak so as to not ruin anybody's game haha
Thanks for playing ^.^
