There's definitely something there. The graphics kinda reminds me of the early kings field games.
The controls are pretty rough tho. I think having a crosshair or something like that in the middle of the screen and adding mouse movements to look up and down would help a lot.
I touched the cube that turned all the eyes green but then I got stuck and couldn't figure out what to do next.
It's a good start for a game. The atmosphere and graphics are there for sure. I would just work on the controls a little more.
