In V0.3 I added a ! marker above player ahead when the waves about to change.
Mini game length is always hit or miss, some people like it and some people don't.
Same goes for difficulty as the general sense = "It's to easy" .
That's why I add easier games in between harder ones
And shorter games between longer ones
Not all mini-games are for everyone and will never be the case.
I can't please everyone with everything and that's harsh reality.
On a side not V0.3 has a custom wager girl as test (and it's extremely buggy)
Hope your happy with this information?
