First person puzzle games must be so hard to put together, so I immediately salute you for that effort alone!
This game is awesome. The visuals are gorgeous, the relaxing music helps to keep a lid on my raw emotions when I'm failing miserably, the puzzles are all doable but still challenging enough to cause some head scratching moments and the little hints of a plot underpinning the whole thing is a nice extra surprise.
I really do adore what there is of this game so far, it's got bucket loads of potential and I'll be around to see you get there! My only suggestion would be to maybe include a few extra options with regards to graphics quality because my poor potato PC stumbled a few times during my playthrough haha!
Keep up the awesome work, I'm gonna get back to trying to beat the last few levels I haven't wrapped my brain around yet =)
