Keyboard and mouse

Source: Steam
Sunny Side Down, by Muno! puts you in charge of a tiny mouse worker at a breakfast diner, guiding eggs toward a frying pan while a line of customers waits overhead. The game is still Coming Soon, so the final default keyboard bindings are not yet published. What is already confirmed: the game is single-player with Steam Achievements and Steam Leaderboards, so the controls you settle on will carry you through score runs and long shifts alike.
Sunny Side Down is a frantic arcade puzzle-platformer where you're a tiny mouse working at a breakfast diner, guiding eggs toward a frying pan while a line of angry customers looms over your head.
Until Muno publishes the exact key list, expect the keyboard layout to cover three jobs:
Movement and positioning: keys for moving the mouse around the diner floor and lining up with incoming eggs.
Egg interaction: an action key or two for nudging, carrying, or dropping eggs into the frying pan.
Pause and menus: a pause key that stops the shift instantly, which matters when the customer line is about to break.
On launch day, open the options menu before your first shift and read the keyboard layout screen. Because rebinding support is not confirmed, plan to play with the defaults unless the developer announces customization later. If the game follows common PC arcade conventions, movement will sit on the left side of the keyboard with an action key near your resting fingers, but verify the displayed bindings instead of relying on habits from other platformers.
Gamepad (full controller support)
The most useful control fact on the store page is full controller support. That means the entire experience, including menus, pause screens, and leaderboard browsing, is designed for a gamepad, not just the action sequences. For a frantic puzzle-platformer that rewards fast input, this is the recommended way to play if you have a pad you trust.
The standard layout for this kind of game usually splits control duties between the two hands:
Left stick: moves the mouse worker around the diner.
Face buttons: handle egg interaction and the main action tied to the frying pan.
Shoulder buttons and triggers: commonly used for shortcuts or secondary actions, and for switching tabs in menus.
Start and select: pause the shift and open options or leaderboards.
Since the game has full controller support, the on-screen prompts should swap to gamepad icons automatically when a pad is detected, which makes it easy to learn each action while the customers are still calm. The single-player design also means you never have to share the pad or coordinate inputs with another player, so you can tune the setup purely for yourself.
If you are torn between keyboard and gamepad, think about the customer line: it never stops pressuring you, and keeping both hands on one controller tends to feel more natural for quick left-to-right egg corrections than reaching for keys.
Switch input devices between shifts, not during one. The egg you are guiding does not wait while you search for a second controller, so settle on one input method before you start the next run.
Tips and rebinding
Rebinding support is not confirmed for Sunny Side Down, by Muno! so treat the game's default bindings as the layout you will probably keep. That is easier to accept than it sounds: a game with full controller support usually ships with a thoughtful default map, and you can still adjust some inputs through Steam's controller configuration before launching the game if your gamepad is supported there.
Until Muno publishes the defaults, a few habits will save you time:
Read the controls screen first. Even if you want to jump straight into the chaos, one minute spent confirming the pause key and the egg action key will prevent fumbling later.
Practice before chasing leaderboards. Use a low-pressure shift to learn which button moves eggs toward the pan quickly, then start worrying about Steam Leaderboards placement.
Prefer small movements. Guiding eggs in a crowded diner is about precision, so tap the stick or keys gently instead of mashing.
Watch for future options. Because the game is Coming Soon, check the game's Steam news page after launch in case Muno adds rebinding or alternate layouts in an update.
If you pause as soon as the shift starts, you can read the exact control prompts without losing an egg. On a frantic diner floor, a calm look at the bindings is worth more than a rushed first attempt.
