@darkniko to kill the bubble boss, you have to collect a bubble in the same color as the bubble of the boss. Your shoots should have that color as well then.
The Invert-Time Task at level 1-7 is pretty much impossible, since about 50% of the time I'm upside down isn't count as invert. Does the car has to be exactly horizontal or what am I doing wrong?
One suggestion for this really great game: Could you add a timer, that shows, when a skill will wear off? Especially for Shadow Walk. Apart from that, I absolutely like your game, keep up the good work :)
