like the game, like the way that you have add text to object and give some information about what they are, also like the different rang do the props that you have use within your game. and the layout of the level so that you are able to walk around to different one and that they are not fixed.
improvement that there could be a bit of sound that play in background or when inaction with the object that you have in the level, could use some texture on the wall of you level like something different for each are.
other than that great work
