its cool game but, i cant buy anything even tho i have enough money. wil you find out why?

This game is cool.
But wow, art is special... maybe you shouldn't resize your sprites, it pixelates them and it's not pleasant to watch.
The thing which upset me totally is your texts. I cant' see my score ! Your background is brown, and the text is brown, so how can we see it ? I gave score as example, but it's the same for every texts.

"Game is extremely difficult". I don't think so. I scored 6442, i don't know if it's a good score but i think i have reached the 5,000 you told.
I had to try a lot, because sometimes rocks of both side are joined. I don't have any way to go through. Nevertheless, it's addicting.

I assume that the rocks on the way are random, but not so rarely they are blocking the entire way, so there is no way you can get pass them.

this game sucked

Uhm. Well the music is good at first but once it reaches a certain point and it has that high pitch noise in it, sort of ruins the flow. Seems a bit slow paced. The powers for the <<Zombie Miner>> are bugged since I only got one life. The boulder system is a bit off such as when falling and a boulder falls and blocks of the way down which makes the game a tad un-winnable. When choosing characters the sprites for them are really low textured than you would want them to be. Not a game that I would play over and over again. Maybe add items that you can get while falling for points or a boost. Try adding more characters and better powers. There are also a few spaces in the descriptions for the characters that shouldn't be there. Also not sure if this is intentional but when I press the arrow keys on the menu the neon miner begins to float and the rock beneath it slowly sinks. The Background textures are phenomenal but the other textures are really blurred. Best of luck to yah and sorry for that bad Critique.
