Nicalis, developer of Cave Story, has announced on its official blog that the team is now in crunch mode and expects to release the game in either late April or early May. The online manual is being written, final testing is in progress, and all of the new artwork is being scrutinized. The audio guys are working on a speed synthesizer that will sing lyrics over each song in the game. Also mentioned are plans for downloadable content.
Cave Story originally appeared as a freeware PC game in 2004 and is now being produced for WiiWare. It features classic platforming gameplay similar to Blaster Master or Super Metroid.
