Prototype 44 - Minor updates

I'm excited to be back to work on this project! This is a relatively small update but expect to see more coming in the future. Minor engine updates, pressing the cancel button now closes the shop menu, some debug features have been re-enabled, etc. Also I have removed solo and duo modes for now as I really want the focus to be on full party play. Please give it a download and let me know what you think by filling out our brief questionnaire!
