Thanks, I tried to make sure that the gameplay loop is fun but I didn't want to make it too hard to get into if a general strategy is not obvious to a first time player.
Didn't want people to be put off it it was balanced to a T but only for people know know what to do.
The difficulty does scale infinitely so I figured that surviving for as long as possible let's people who are more or less comfortable still push it to its limits.
Thanks for the feedback!
