On the left is part of the N503i phone running a Java game. The 503i series is a set of Japanese cell phones capable of handling the i-mode system and a special type of Java applications.

This i-mode Java standard, which is a rival to MIDP (see e.g. MIDP-Man) was developed by NTT DoCoMo and is commonly referred to as DoJa.

I built this game mostly as an experiment, to see what these cell phones are capable of. People who happen to own one or have an emulator installed may want to check out the ingredients page for the program and the corresponding JAM file.

Click on the "i" button to start the game. Then move the penguin using the cursor keys.
