Thanks for the feed back!
I made this game as part of a schooling project but I would like to go back to it and fix some things and finish it.
As to #1 i have also had comments about it being too dark! So I believe that it is a balance i need to find.
#2 again I made it in about a month and it was the easiest way to do the enemies at the time. I would like to go back and add proper pathfinding and some state AI to them.
I do appreciate the feedback and have made some notes for these issues.
Glad you enjoyed it!
