Punch Ball Antonball Classic

Punch Ball Antonball (later referred to as Punch Ball Antonball Classic) is a platforming video game developed and published by Summitsphere and released on Itch.io. It is the second game in the Anton series. The game is a noticeable shift in gameplay style, resembling the Hudson Soft-developed PC game Punch Ball Mario Bros. 

Due to the game's poor quality, Punch Ball Antonball was delisted from Itch.io in December 2021.

The gameplay of Punch Ball Antonball was later iterated on in Antonball Deluxe under an identically-named mode.

Gameplay
Instead of using a small ball to break down a wall to Anton's right, Anton instead uses a larger ball to stun Ballbusters, which he can then defeat by simply making contact with them.

The final two levels have some unique quirks. Level 6 only has a single Ballbuster to defeat, while 7 will go on indefinitely, effectively making the game unbeatable.

Development
Punch Ball Antonball was developed solely by Robokai in merely a single day.
