A bit of context: we didn’t make the game intentionally difficult to play with a keyboard or on PC, but the game was conceived and tailor made to be played with a controller.
The game was originally conceived for console, the original version was actually developed initially for PSVita / PS4 / Wii U back in the days. And yes, the control system is made to work as intended with an analog input system.
If you try the game, you’ll pretty much see immediately that there’s no way to replicate the feeling of controlling the probe with digital inputs: you pretty much need an analog stick to play it as intended.
Sorry for that, but it was a design choice, so yep, while the game is fully playable with M + K but we know it’s not ideal and there’s no way to make it ideal.
