General Game Features:
🪐 Survive waves of darkness
Defend the crystal against increasingly chaotic waves. Every enemy counts and every decision matters: if the crystal falls, darkness will consume the cosmos. Use your wit, your weapons, and your flowers to survive. Explore, grow stronger, and prepare yourself to reach wave 100… if you can.
🔫 Crazy, evolving weapons
From a flamethrower trumpet to dynamite-stuffed plush toys. Every weapon is unique and comes with its own mechanics. Level them up, evolve them, and change their behavior — the more you use them, the more devastating they become.
🌸 Grow your own space garden
Plant and discover flowers with unique effects: generate resources, poison enemies, heal, grant experience, or activate worker bees to automate everything. Protect your garden… enemies will target it too.
🃏 Tarot cards: temporary powers
At the end of each round, choose one tarot card from three options.
Gain temporary powers that alter gameplay, and combine up to two cards to adapt to every situation.
🧠 Over 100 skills to shape your playstyle
Unlock a massive skill tree that enhances Romby, your flowers, and the environment.
Choose freely and in any order you like!
🌌 Discover constellations and explore hundreds of areas
Travel through space and uncover constellations filled with areas, secrets, enemies, bosses, and powerful rewards.
