Also i just found out that explosive bullet says it costs 0 coins
Also level 10 finished with one enemy alive
11 did the same
12 can't finish there are no enemy's yet it doesn't end
It also finishes with one enemy when I retry
Most level after 10 end with 1 enemy left
16 ended with 2 or 1 alive
On the level select if you scroll up too mutch you get stuck
