My space key was not ready for your game. XD
I liked the concept, though: simple and addictive.

Fun and simple :) I like the retro aesthetics but my space bar hurts from attempting this xD

Played and rated! It was really fun. At first the first screen was a little bit irritating, but then I understood the "rhythm" of the game, and everything started being really fun.

I got only to block 8, but I will now try again to beat my score.

Movement feels really good! The level design is also so varied for 48 hours. Lots of different gameplay.

Addicting! Really addicting! Simple concept but well executed. The sound design was on point. Really made the experience funnier with the splashing puddles etc. Great game!

Hah, impressive! I would never think one button game can be so interesting. I had a lot of fun playing this game - unfortunately my endurance is so week that after 10mins of gameplay I had to stop hahaha. I will definitely be back to play some more :D

Realy nice pixel art!

Nearly broke my keyboard :D .. Loved the art style..  hated the full width spikes level..

Good design and original, Concept is cool and has a lot of potential. Good work!

Very cool idea! I only wish there were some ideas on how to develop the game further with this concept. Other than that, great work!

Awesome way to really stick to the theme and making one button game really come to life. So far one of the most original and better games I've tried! 

This is the kind of game that makes me go: "oh, I get it". It's very simple and intuitive and a great concept. Nice job!

Big fan of the artistic style on this one as well as the game play 

A fun little game, kind of takes the "only one" to the next level.

Nice game!

I think i broke my keyboard...  ;) Great effort from dev...

Not really an endless runner. Unless you count endless tries at the game as well. :D Took me a few tries to understand what's going on, but... it's stacked with clever design decisions! <3 Spikes coming out of the ground force you into precise movement, so you cannot simply button mash. But don't be too slow either, a red lookalike of your character is right behind you! He might get hit by a piano though... :D It won't have any fall animation ("only one" frame) so better make sure, you're not surrounded by a bunch of red exclamation marks. Oh and btw: the levels are randomized, so good luck finding any patterns! Sadly that's also the biggest weak spot of the game: the difficulty curve can feel a bit off a times and after a few times.Amazing little timewaster, honestly did not expect this to be so good!

Got until 10 blocks then my hand said I had to stop smashing space haha

5 blocks is my best... : (

Simple but very fun game...I like how the character walks and the effort you make to let the game feel juicy.
Nice work!

Made it to 14 blocks! I switched off between two fingers for maximum space mashing. I think the difficulty could be ramped up a bit after 4-5 blocks but a very enjoyable experience nonetheless!

looks good, super fun, very original! one of my favorite games this year so far.

Think I broke my space key! Fun and really fits the theme!
