WHY!?
You made some odd choices with this game. I admit its pretty fun thanks to the charming graphics and great sound design.
But why would any one want to buy diamonds? And the highest you can buy at one time is 500 diamonds... Why!? There are only two things in the game I can buy with diamonds and thats the 2 guitars which are priced at 1000 diamonds each. And you even have lower amounts of diamonds for sale which is just pointless, why would I want them if I cant use it right away when I have to save up to 1000. I rather buy 500 at a time so I can actually DO something with it. Or why not just buy 1000 at once.. Instead of making us do 2 transactions. It just makes no sense.
UGH, its just so strange that you did this.
Another thing is, why are there so many weapons that are the same price? It doesnt make any sense.. I have to grind hard to get tons of cash but I can only buy a new weapon once every 10-20 minutes since the prices arent spread out enough. Then once I buy 1 new weapon there is absolutely no point in buying the others of the same price since it doesnt show me the stats until after I buy it so I assume its the same as the other ones, so theres just no point.
I suggest spreading out the cost of the weapons so you can buy more quicker. This way it will feel like you are progressing faster, instead of being stuck at one point for a long ass time.
Also seriously have a better reason for diamonds.. As of now, its kind of a joke.. Unless there is something I am missing..
Other then all of this, you did a fantastic job. :P
