@SHNiTZEL68 I got pass that metal door by luck... I was in "hyper speed" and not long before the door I got a Rocket Rider and BUM! got through and got my wallet back.
I managed to get 13 crystal so that I could craft a 10 crystal item. After the process I was left with none. What the...????? OK.. this game has potential but overall - 2/5
The rare items from the shop have a ridiculous price, but if I get enough gold to buy one, guess what, the price has tripled. So everything in this game is forcing you to use cash to get something.
Whoever thought the logic in this game is a an douche. Yeah , I said it.
One thing that would be helpful is to have some hp recovered after each battle. Otherwise you have to repeat over and over again the last 2 bosses. Lame.
