sell option would be great, i find its a lot of grinding :/ shop needs to change items not just stay the same until you get to next chapter, overall good game, needs a few touch ups 4/5
you should atleast be able to buy some backpack/ chest slot for crystals not just diamonds :/ even if its like 10k/100k/500k ect each. + to keep this alive :)
how come the second boss gives less money than the first?? anyways, some possible badges get #killse in bullet time "some matrix refference :p" complete the game "death of all monsters/ like a boss" and ill try to think of more :) happy gaming
