ninjas need to only vansih for 3 seconds not 5 it lets them bypass all of your upgraded defences and sometimes get a gem on the last level they have to be killed by rain fire to get brilliant
the last level ninja boss is too hard, it vanishes at the start and gets the gem then gets about 1/2 way back you need to fully upgrade meteor to kill it
i rally like this game but it takes ages to get skill points, why not give them for achivements or like 5 per level because you spend ages grinding and grinding just to get +15% blaze or something
i killed a big thing that filled the whole bubble, and was like this was easy to find, killed it, no achivement, i was like woah how big is gorram gonna be?
