This game is now on, Try to beat my time!

Hey, that's so cool! Thank you so much for speedrunning the game, I'll try and attempt to beat it :)

I'm actually developing a spin-off of this game that is more focused on skill platforming and speedrunning, so stay tuned for that too.

Awesome! I have no doubts that you will beat it. Who would've thought my first competitor would be the creator? Thank you for making the game. This was actually my first ever speedrun submission. I really enjoy your (and your musician's) work so much I couldn't pass up the opportunity to become a World Record holder.

I can't wait to see what's in store for your future projects! I'll definitely be planning on running (and moderating runs) for games of similar like. Best of luck to that project ^-^ 


I love the characters' voices and wonky music, it's such a fun combination.

character's voice ?


excellent game , finished but not perfected ... yet !


This was the most enthralling story i have ever witnessed in a videogame.


got the cake, saved the day :-)


has a nasty tendency to respond twice to a single press of "Z".


Nice game!

One wish: level select screen to let me quickly go to any level where I missed a coin. And a restart level, just in case I exit it by accident while trying to get a coin.

One typo: "convinient" should have been "convenient".


This is charming! I love the sounds, and the challenges are interesting. It got difficult!
