Alley Cat is a platforming game that was initially developed for Atari 8-bit computers before being ported to IBM-compatible PCs and the PCjr. You play as a stray cat that is out to cause trouble in ways cats are typically known for: eating other pets' food, eating live fish, mice and birds, and knocking over hung laundry. In some stages, there are dogs that are out to get the cat and animated brooms that are there to get in your way. Thankfully, there's someone special waiting for you at the end of all this trouble.
In this run, eien86 sets the difficulty at the highest setting and plays through every unique room as fast as possible, uniting with stray cat with his love Felicia.
