I find music actually alright but also agree with another user the mute button it would be good idea. Also the colours are too dark it would be better just add a bit of brighter. Game seems not bad at all but need strong improvement and changes to keep users happy.
Not bad at all, but game need few elements to add and change. By the way when enemies running it seems begin some sort of glitch also it would be better if you can move with all mouse such as looking around not only left/front/ right but also looking back it would be good.
