Theme: The Sky ☀️☁️ and the Sea 🌊🐚

☀️ Summer time is here - and there's no better time to travel somewhere on a plane, sail the seas, go diving or even go further below...

So let’s make games about the sky and the sea! Any game about the sky and the sea is welcome, whether it's a hot air balloon ride, and airplane flight simulator, a sailing simulator, a surfing racing game, a submarine simulator, a hang glider simulator, a skydiving simulator, aerial combat simulator, a pirate game, a snorkeling simulator, you get the idea! The Sky's the limit (literally, in this case!).

🎯 Limitations (Pick 1 or more!)

Choose at least one limitation from the list below. Each one is a “modifier” to your Sky and Sea adventure — mix and match to create your own unique journey. You can choose more than one if you like, but one is the minimum.

1) 🌩️ Gods & Goddesses of Sky or Sea

Your game must feature, reinterpret, or be inspired by a deity connected to the sky or the sea. This can be literal mythology, loose inspiration, or a creative reimagining.

Examples:

• A boss inspired by Zeus who controls storms and lightning.
• A survival game where the tides are controlled by an angry sea god inspired by Poseidon.
• A narrative game where the player is a forgotten sky goddess trying to regain followers.
• A rogue-lite where different sky or sea deities grant temporary powers.
• A fishing game where the ocean god must be appeased before storms calm.
• A platformer where the wind itself is a sentient sky deity guiding (or sabotaging) you.

You can draw inspiration from any mythology:

• Greek, Norse, Egyptian, Polynesian, Japanese, Chinese etc.

2) 🌊 Lost Civilization (Sky or Sea)

The player must discover, explore, survive within, or originate from a lost civilization tied to the sky or sea. This can be ancient, futuristic, mythical, or post-apocalyptic.

• Searching for a golden sky temple inspired by El Dorado.

• Wings forged from storm metal.
• A conch shell that summons rain.

5) 🌊🦖 Titans of the Sea (e.g. Kaiju Battles)

Your game must feature a large-scale battle involving a sea-based titan or kaiju.

The Kaiju must:

Your game must meaningfully incorporate exploring a sunken ship, ancient shipwreck, or ghost vessel.

The ship must:

• Gameplay mechanic (platforming, resource gathering, exploration)

It must feel significant, not just a background decoration.
