Chrome and Chromium dropped java plugin compatibility. If you are having issues playing the game i suggest you to switch to some other browser because there's no fix incoming, for chrome at least.
I don't think anyone would choose to cancel a power up to start the rush, since you are in both cases invulnerable i think you should be able to use the rush only after powerups are completely vanished, making it impossible to waste them
To all people complaining about the letters: the game would be way too easy if you didn't lose letters! It's just fine the way it is i think. Really awesome game, I love this genre of flash games!
In every game like this i always get a few point into fire attack+ damge then i go straight for magnets xD picking up things always get me to suicide haha
What to say? :D it takes a while to get the hang of the controls but once you figure out how it works i know it was worth it! a lot of ingeniously made levels to play
