Hello!
This has a good idea behind it and it shows good game loop mechanics in the planning. A few things I found though, the controls only move the character with the arrow keys. This makes pressing E difficult but maybe it's just me =P.
There's a lot of open areas with no objects to find which makes it feel a bit empty. Also at the end I'm unable to see the mouse to select replay. Might just need to change controller inputs? The theme seemed a little loose =P.
Best advice I ever got was test, test, test. Get your friends to try it out and you'll be surprised what they can find. Overwise nice going dude you show good understanding of clean model and simple level design. GG
