It's been reported that some built in keyboards on android devices have incompatibilities with Colleen. You can solve this problem by installing Hacker's keyboard (available on Play Store), or using a normal hardware keyboard. By the way, I've contacted the author to report other compatibility issues, such as the 16-bit sound, which is unavailable on latest Android OS (i.e. 4.1, 4.2). First time it works, but if you exit the application and run it again it is gone. And 8-bit sound is terrible on modern devices. You can fix this reinstalling the app or cleaning the data from Application Manager. But it's a pain to lose your custom settings everytime you want to play again.
