FLOAT is an app that explores the issue of river litter.
In this version, you can play in four different rivers: the Arakawa River, the Nile River, the Yellow River, and the Mekong River.
[How to Play]
1. Choose a river.
2. Tap or swipe to create waves, move the litter, and collect it in the white basket.
[Time Warp]
With the Time Warp feature, you can travel back in time.
The types of litter and the creatures you encounter will change depending on the era.
[ZEN Mode]
Tap the switch in the upper-left corner of the play screen to open the options menu.
From there, you can turn on "ZEN Mode".
[Connecting the Game to the Real World]
By watching ads, making in-app purchases, or buying NFT art, you can support real-world river clean-up efforts.
Our team will actually collect litter from real rivers.
The following options are available:
#Plan-A
Watch a 30-second video ad
- Receive 4,000 in-app coins
- Our team will collect 2 pieces of litter from a real river
#Plan-B
Unlock 1 stage ($0.99)
- Our team will collect 4 pieces of litter from a real river
#Plan-C
Unlock all stages ($9.99)
- Our team will collect 15 liters of litter from a real river
*Any future locked content will be automatically unlocked after updates.
#Plan-D
Purchase special NFT art on OpenSea (FLOAT-RiverLitter)
- Our team will collect 1 liter of litter per 0.002 ETH
*Prices vary depending on the NFT.
*The collection amount may change if the price of Ethereum fluctuates significantly.

*Please note:
In Plans B and C, litter collection is a secondary feature. The main benefit is unlocking game content.
For now, clean-up activities will take place on the left bank near the mouth of the Arakawa River (about 3 km upstream from Tokyo Bay), where litter tends to accumulate.
[Activity Reports]
You can check the total number of ad views and purchases on our website.

This project is a social experiment.
We will continue improving it through trial and error.
All proceeds will be used for practical and educational efforts to address river and ocean litter.
[Notes]
#1 About Plastic
This app does not promote eliminating or avoiding plastic.
Plastic is a useful and important material in modern life.
We believe the real issues are:
- Illegal dumping
- Improper waste management
- Excessive use
#2 Performance Tips
If the water movement feels heavy:
Tap the gear icon on the title screen → tap the monitor icon → set graphics to "MID" or "LOW".
