nice game but the attack is a bit wierd.
it either you have couldown on attacking or it just sometimes doesnt work

another issue you got,
you can move with awsd
and W is a super power
i guess you should dissable moving with wasd.

another issue.
would be the shop it hart to tell if you are on trade or not
maybe do a T press or something to confirm the buy
because you dont actually use the mouse in the game,
yet it much easier to press trade then wonder if it's on it.

maybe do that 2 times press on same buy power would automatically trade.
