Peggle meets Isaac: a roguelike run through 58 Isaac levels, with random Isaac items from every green peg.
Peggle, with The Binding of Isaac's characters as Peggle Masters.
Adventure: a roguelike run through 20 Isaac levels from the Basement to the Chest, with a shop between levels. Afterwards you can go on to 38 bonus levels: Alt Path, Secret Rooms, the Horsemen, the Deadly Sins, Endgame bosses and Iconic shapes. Orange pegs and coin pegs earn coins, now and then a double penny or a nickel. In the shop you can buy starting items, extra balls and rerolls, or take a devil deal (sometimes an angel offers a gift instead). Random Run plays 20 levels picked at random from every pack, and you can keep going after that. Both runs are saved so you can come back to them.
Item Room: every green peg gives a random real Isaac item, with its real sprite and sound. There are 66 items, including every Peggle Master's power as an Isaac item: Super Guide, Multiball, Pyramid, Space Blast, Flippers, Spooky Ball, Flower Power, Lucky Spin, Fireball and Zen Shot. Devil and angel items come from their own deals, and green pegs can roll them too.
Levels: each level's boss sits in the background, while its attacks (tears, flies, bombs, scythes, coins) move across the board. You'll also find spinning pegs, rock platforms and Isaac's portals.
Real Peggle: the cannon under the Master's orb, the aim guide, the Free Ball bucket and Free Ball meter, style shots (Long Shot, Off the Wall, Orange Attack), the Fevermeter, a grace coin with angel and devil statues, slow motion on the last orange peg, Extreme Fever and its bonus pits, and Ultra Extreme Fever for clearing every peg.
Also: 12 challenges with ribbons to earn, Free Play by world and pack, and "Who am I?", where you can pick any Isaac character (this changes looks only).
Solo. Needs Peggle Deluxe and The Binding of Isaac: Rebirth installed: everything Peggle and Isaac is read from your own copies, and nothing is copied or shipped. Peggle of Isaac plays Peggle's files with its own rebuild of Peggle's rules, so it never opens the EA app.
