Guilty! Because good game design involves a lot of editing. :)
With each pass at adding more levels I've also looked at all the levels, to see if the set made sense as a whole.
Here are some types of levels I've deleted:
- Boring levels. Just a flat map and some enemies. Deleted!
- Difficult levels. In one update bronze and silver were made easier.
- Flawed levels. There was one that involved a lot of running around next to saw blades. Was more tedious than tense. Deleted!
- Repetitios levels. In the first pass at Endless Mode there were a lot of levels that were subtle variants of eachother. Once we had more levels I cut down on duplicates for a fresher experience!
Thanks for the interesting question! :)
