You could have mentioned that "do a 10 seconds wheelie" doesn't actually mean that, but instead means "do wheelies for at least 10 seconds total", meaning that 10 one second wheelies is okay too! :O
Why exactly can't I click, after placing the X, just click somewhere outside the object? And not have to click on the onject again?
Since most objects are quite small I have to repeat this countless time before they have moved a significant way :-(
As it seems the grey bubble thing always happens right after you bought an upgrade.
Going to the menu and back to the level again solves it.
And the 9000 score is really hard to get. Especially since the grey bubble stops to work at 4000, meaning that you can still shott it but the score no longer increases. And once you get around 7000-8000, you are literally surrounded by at least 8 of the really big turrt guys wth their triple homing shots. Really hard, man! :O
Yes, sorry i'm just uploading a new version with a fix!
