Party Time! Hexcellent!'s Rachel Weil has released TRACK+FEEL II, a free Nintendo Entertainment System homebrew title playable in NES emulators and on original hardware.

TRACK+FEEL II is a freeform music game for one to four players, and requires use of both the standard NES controller and the Power Pad mat peripheral. The ideal setup is for two players; one player cycles through a variety of music palettes and background art using the control pad, while the other generates tones using the 12 buttons on the Power Pad.

In a great twist, the player with the control pad can also introduce glitches, leading to unpredictable background corruption and all sorts of unique sounds. It's good stuff! PowerPak owners: this is your jam.
