Hey everyone!
I'm 13 years old and making a multiplayer co-op game called Vivarium completely solo in Unity.
I shared a text post earlier asking for feedback, but without visuals, it didn't get much traction. Today is Day 4, and I wanted to share actual gameplay video!
What is the game about? You and your friends play as scientists in a secret lab working for the government. Your mission is to conduct experiments on a massive biological cell using different chemical tubes/syringes. Each tube injected into the cell triggers different reactions, mutations, or hazards!
What I added today (Day 4):
- Added character models and movement animations.
- Synced movement & animations across the network for multiplayer co-op.
- Fixed various lobby and gameplay bugs.
I need your ideas! I want to create a wide variety of test tubes/syringes to inject into the cell. Right now I have:
- Size modifications (Enlarge / Shrink).
- Physical mutations (Growing arms, legs, tentacles).
- Emissive & RGB color shifts.
What strange, funny, or terrifying effects should other test tubes cause when injected into the cell? Would love to hear your ideas!
