Tyrone Rodriguez, creator of games like Cave Story, has revealed some info for The Binding of Isaac: Rebirth. In the post, the developer discusses the button layout for Playstation versions of the roguelike. While the game is known to be made by Edmund McMillen of Super Meat Boy and Indie Game: The Movie fame, Rodriguez is a part of the team on this title as well.
In The Binding of Isaac: Rebirth, players can fire tears in multiple directions by using the analog sticks, while directional buttons can also serve for movement. Using a bomb or a pill gets mapped to the shoulder buttons for both Playstation 4 and PS Vita. In the latter case, however, the fewer shoulder options relegated the use of an item to the Select button of the handheld. Map size can be altered with the front touch screen. The Binding of Isaac: Rebirth won’t use the back pad of the PS Vita, because the developer felt it wasn’t precise. Moreover, as button layouts can be configured, this is just the standard setup.
Further on in the post, Rodriguez discusses random seeds for the game. A short clip shows that the random generation is dependent of an 8 figure code. This code includes all alphanumeric options except I, O, U, and V, as the developer felt they looked too much alike. That’s a pretty nice move, actually.
A slight fraction of randomness is taken away with the addition of seeds in The Binding of Isaac: Rebirth. This shouldn’t be too much of an issue though, as the post mentions the following:
In Rebirth, the seed determines every floor layout, room, enemy and item in the run. There are 2^32 – 1 or 4,294,967,295 possible seeds—over 4 BILLION combinations.
This move is pulled so that playthrough sharing becomes easier between people wanting to try on a similar experience.
Some of the post also discusses why The Binding of Isaac: Rebirth uses a resolution of 480 by 272 and comments on the fact that the Playstation versions will run at 60fps. For comparison, the Flash version ran at 30fps. Additionally, the PS Vita edition is stated to be ideal for mobile players, since it won’t be able to process all the visual bells and whistles that the Playstation 4 is able to produce.
We finally got into The Binding of Isaac over the Steam Summer Sale. We were terrible at it, but it’s fun, give or take a few glaring issues with the game. You can see the gameplay session below.
