A game by TCHOW for PC, Mac, and Linux, originally released in 2013.
The name Rktcr is a disemvoweled conjoining of the words “rocket” and “car”. The game features a rocket powered vehicle traversing a number of complex subterranean environments, and gameplay is entirely physics-based. That’s not to say that the game offers a few physics-based puzzles here and there, or that the action is interspersed with isolated sequences where you might shove over a pile of blocks to watch them roll and tumble down a slope; rather, every bit of the gameplay centers on the player’s understanding of how the rktcr works and how it physically interacts with the environment.
At the start of the game, you create a team, customizing three characters and a rktcr. However, customization is done in a fairly strange way in that it is driven by the names you provide… By typing a name, your character begins to cycle through a number of visual styles, changing clothing, ethnicity, gender, etc. with each typed character. Even upper and lower case letters affect the look, cycling through dozens upon dozens of possibilities for the characters, and a number of visual themes for the rktcr as well.
