About the game

Seabun is an incremental 2D survivor-like with creature collection elements, where you play a scientist bunny diving deeper and deeper to find the source of the sea's corruption. Haul your loot home between dives, grow your lab, and raise the fish you rescue into rideable mounts.

Original Steam description

Designed and developed by Moon Buns, with art by Blobfish

Dive into corrupted waters

Something is wrong beneath the surface. Play as a scientist bunny in your tiny armed submarine and descend through infested depths to find the source of the corruption one dive at a time, each one deeper than the last.

Equipped with your auto-firing loadout, make the most of every dive before your oxygen runs out. At the bottom of every depth, something big is waiting.

Come back stronger

Every dive improves the next one. Spend your hard-earned resources filling out a vast upgrade tree, craft and upgrade modules in the workshop, and push your build from a lone harpoon to a screen-clearing arsenal, then dive back down and see how much further it takes you.

Grow your lab

Between dives, your lab is alive. Hatch the eggs you bring back, feed your fish, and raise them until they evolve into rideable mounts, each one changing how you approach the next dive. Your fish keep earning pearls even while you're away.
