I wish the rounds were much shorter - it could get tedious while waiting for the next wave without any new enemies or upgrades to keep me busy. I was always looking forward to the next twist however, as they never failed to keep me on my toes!
Thanks a lot for the Feedback :D. Agreed, there are certain things that needs fixing. I will be fixing those and adding some new features in my free time. Stay tuned if you are interested.
