Oh no! Tiny Sub has fallen into an underwater cave system! There's ONLY ONE way out of this, because Tiny Sub's engine functions in ONLY ONE direction! Thankfully, it takes ONLY ONE button to control: press Z to propel yourself forward and up!

Really good ! I really like the atmosphere and the end was very cute :)

(I'm sorry it took me so long to see this comment!) Thanks Adrien, I'm glad you liked it!


I don't know if there were mutliple level or just one long one, but I would have preferred multiple shorter levels or some checkpoints. The art and sound was nice though.

Cheers mate! I was tossing up that idea - also the idea of making it endless! I'd probably consider adding some difficulty options to adjust those kind of things if I was making it again. If you're curious - it's one big level, which takes about 2-3 minutes to get through, with a little ending after that :)


This is so amazing! The gameplay is really great and the music is so perfect. Really love the artwork as well! Fantastic work all around.

Thank you! I really appreciate you taking the time to check it out! :)


I love your starfish! 


I love your underwater world!


So cute!

Cheers mate!
