First a brief intro about myself - I'm the artist/designer/scripter/+more behind Dear Esther (the retail release).
I started out making maps in the hl2 modding scene and slowly worked my way up and eventually landed a job as an environment artist at Dice, working on Mirror's Edge. I worked on the Storm drain (level 2) and Shard level (Last level) and well as most of the DLC - Timetrial Map Pack which followed shortly after it's release. After it was completed I decided to take some downtime and return to the UK to spend time with my family and plan my next move. I wanted to do a small side project during this time to keep my creative juices flowing, and whilst searching for inspiration I stumbled across Dan Pinchbeck's experimental mod, Dear Esther. Originally starting out as a simple visual overhaul it gradually evolved into a fully fledged indie title. It's been an extremely tough journey, but ultimately a rewarding one, and with the recent Steam sale helping us reach a whopping milestone of over 100k sales last night, I thought it would be nice to reach out to everyone who've supported us and helped us get here and do a bit of an AMA for anyone interested. :)
I will try to answer as many questions as I can, hopefully Dan (writer and creator of the original Dear Esther) will also be able to drop by at some point to also answer any questions regarding the more deep philosophy and thinking behind the game. In the meantime, though ask me anything!

Ok some great questions here, hopefully I answer a good bulk of them! Going to call it a day now, I've been at this for 6 hours straight, I'm exhausted! Thanks for all of your questions and your time, and I hope you enjoy the game! Oh and dont forget it's also 50% off on steam right now until Thursday 4pm (PST)! :)
