Unique idea, but as others have said its more frustrating than fun. It reminds me of how people do blind speedruns of games, like in this video. To that end; I think it would be more enjoyable if you got a glimpse of the level before it goes dark and there were more audio queues (sound for moving, sound for bumping up against the wall, etc.)

this is a really cool idea but also it is super difficult! the metronome was a great tool but i still struggled on the more complex levels

Cool idea, and I love that there's an Android build which I played! It would be nice if the playback could be sped up and maybe showed all of your past runs Super Meat Boy-style, but other than that it's great (except that I suck at not seeing)

really cool game! only complaint is maybe some sort of speeding up the playback and maybe indicators for moving left and right like dashing and jumping are

very challenging but engaging game, I may have spent way too long on the 11th level haha, great work!

Super creative concept, executed really neatly. Great job!! 
I felt challenged but not frustrated, the last level was tough!!

It's very creative, I did struggle a little because my timing was completely off lmao but it was very fun (Also the option to skip the level I was struggling was amazing thank you!)

Tough but fair! Watching the replay after landing a tricky run gives you such a great sense of payoff

creative concept, the levels felt really hard to me though because my lack of rythm control 🥲. But still a nice take on the theme!

creative 

really creative concept and nice execution! all the levels felt super rewarding to beat, though i think it could've used a couple more sfx for a game based mostly on rhythm.

Wow, this is an amazing concept, but damn is it hard, I had to give up on double jump level. Presentation is especially top notch, really pulls it all together.

Super cool concept! I had just left a comment on another game about how visibility-based platforming mechanics are a cool idea but hard to implement. This is a really cool take on that idea! If you explore this idea further,  I think having some more feedback to orient yourself in the world would be nice. I had a really hard time judging my timing relative to falling. The bar at the top of the screen really made this playable for me, I think it'd be nice to be able to drop a marker onto that bar once per level or something (particularly for the more complicated multi-part levels like the last one). Overall, really cool game!

Oh, oh no. I am so weak. I can't to beat the second level :(

Good concept, but I think we might need some onboarding at the beginning.

Super rewarding to FINALLY beat a level (which sounds like was the goal).

I understand why you didn’t include music to not overshadow the steady beat of the metronome, but having something to ground me on each run as like “the start of a bar”, to think of each level as a musical phrase somewhat, and being able to accurately count the offbeat (which I found myself doing anyways since solutions rarely worked for me by only inputting on beat) would be really helpful for being more consistent. But maybe I’m thinking too much like a musician. Overall really cool concept!

nice one

Very unique concept that clearly fits the theme. I could see myself playing it more with some polish, it's quite satisfying to master early sections of the level and cruise through them as you learn the rest. My one complaint is that the controls on mobile are a bit difficult, varying jump height by holding the jump button makes it much harder than if there was a set jump arc.

Interesting concept, but I found myself just spamming jump button and right arrow to hopefully get somewhere. I don't know how enjoyable this game could be, I feel maybe if there was like blinking darkness to the metronome, instead of pitch black? Otherwise, I really enjoyed all the art and the audio really fit the theme!a
