Hey I got the game thru the bundle and I really enjoyed it, I ended up finishing in 20-30 minutes but I think I missed a few things and will probably be doing a reply.
at one of the messages I ended up noticing a window blind moving or something so I was constantly turning to the left to see what was there which was absolutely triggered by your game which you know for a horror game that's a job well done.
I liked the 2D art on the arm you should consider doing another 3D game but like classic doom (i.e. 3D environment with 2D sprites) you would still be handling a 3d environment on the back end of things if you are looking to code for 3D but you don't see many horror in the classic doom style.
