It's like Tetris but with rainbows, unicorns, cats, and much more!

Your mission as a Rainbonaut (rainbow + astronaut) is to power the galaxy by making rainbows. With two equally awesome game modes, you can play endlessly or travel through the galaxy mission by mission, unlocking powerful heroes to join your crew as you go!

Feature Round-Up:

• Conquer 60+ missions or compete for achievements and high scores in endless mode

• Collect powerful Rainbonauts like tricky unicorns, snacky sharks, and gravity-altering sloths

• Unlock new worlds with cat bombs that explode into black holes or gummy bubbles that trap anything that falls in their way

• Check leaderboards to keep up with your friends and other players

• Capture your craziest rainbows anytime with 3D touch

• Select art by the ultra talented Shiroi Room and music by the super-kawaii Maturbo

• The galaxy is always expanding! New Rainbonauts, tiles, missions, and achievements are added regularly

Rainbonauts is fantastic!

It is fun and challenging (but not too hard). The graphics and design are slick and beautiful! The colors jump off the screen and draw you in.

The game controls and concepts are easily understood, leaving you to focus on the challenge of progressing through levels. The difficulty progresses steadily without being overwhelming. The addition of boosters introduces a fun complexity and allows for developing a strategy.

The design is fantastic! The cute characters pull you in and make you excited to unlock more! The cohesion moving from level to level is great and the music brings it all together.

Also the cute stickers are a major plus :)

Definitely a stellar game. Pun intended!

Thank you for your detailed and informed review!

PS - love the pun!

Don’t know...

I thought this game would be fun to play, but I have no idea how to play.

Developer Response ,

Sorry for any confusion! The first level has basic instructions on how to play. Essentially you connect cloud and sun tiles to make a rainbow. Each tile of the rainbow then turns into a spark which goes towards the level’s target. For example, a rainbow made of 3 tiles will give you 3 sparks =). The basic instructions screen also pops up on your first try of endless mode.

There’s also an option to walk through a longer tutorial. The option is displayed on the basic instructions screen or you can go to Settings > Tutorial.

I hope this helps!

Good game but

This game is great except for the AR I know it’s experimental but still it doesn’t even work in the slightest 😢

Developer Response ,

Oh no! Sorry to hear the AR mode isn't working for you. Sometimes it takes a while to find a suitable plane. If you have some spare time, could you provide us with some details about the issue you're experiencing:

We'll try to fix is ASAP. Thank you for playing and supporting us!<3
