Shrinko's Big Adventure
Shrinko’s Big Adventure is a 3D platforming collectathon with deep puzzles where you can shrink and grow to discover secrets, solve puzzles, and explore the nooks and crannies of the island.



Shrinko is a three legged being that has the ability to shrink to the size of an ant and grow to the size of a skyscraper. Use Shrinko’s size to traverse the island rapidly or zoom in on a small feature.

Shrinko’s Big Adventure takes place on an open island with many areas to discover and interact with. Large areas contain puzzles that contribute to beating the game, while small areas are scattered throughout the island for you to explore.
Learn how to utilize Shrinko’s scaling abilities to solve puzzles scattered throughout the island. Press switches, shrink through holes, break glass, and even shoot cannons. Every puzzle is tailored to Shrinko’s unique abilities.
Collect pieces of a collectible like stars or coins to progress. Every area has a unique collectible that raises a mysterious pillar. Raise enough pillars to unlock the end of the game.

I drew shrinko lol <3
This is so cool! I'm adding it to the fridge thank you so much :)
aw thanks :]
oh wow WOW WOW
Zrób lepszy opis gry, bo nie za bardzo wiadomo o czym ona jest. Wspomnienie o eksploracji nie wystarczy. Powiedz coś więcej np. o fabule ( ale bez znaczących spoilerów ).
There's a lot of space, and that's not bad, it's just great. There's plenty of room to roam, to find interesting secrets, it's a really cool game.
I love this game so much. It’s very calming to just roam around and collect things while exploring the diverse areas. The music is also really good; I like how it’s the same theme throughout, but with different instruments added in depending on the area and how big you are. (The dock has my favorite music.) I am looking forward to seeing how this game develops! Really excellent work so far!
That’s awesome, congrats! Yes the camera has issues, but I think you really nailed its reaction to any scale change. It’s feeling very smooth, natural and really produces a sense of scale. There is a sense of wonder exploring all places at different scales that I love. And the aesthetic and music feels cohesive, very familiar and soothing. Love it!
This is pretty fun to explore! Despite having not a lot of puzzles to solve, it’s fun to find the many small secrets. It reminds me of the game Everything.
hell yea
very interested to see where this project goes.
i would sink hours on end into a full game that had Shrinko's grow/shrink ability!
