We opted for an "arcade" style gameplay loop for high replay ability as when we were paper prototyping that was the most fun. Maybe in the future there is an arcade and campaign mode but we will just have to see!
Doom mode started as a joke between me and the artist and I decided on the last day of development to add it in to put a nice lighthearted end to our development for the jam. I'm glad so many people are enjoying it!
Thanks for playing and we are happy to hear you enjoyed your time!
