Necrosphere

Unfortunately I cannot recommend this game since it is pretty much broken for me and for some other people as well. Very early into the game you unlock the dash ability that you execute by double tapping left or right (yes, controls in this game are a bit obnoxious but I'll look at it as part of the challenge), and for real, it just doesn't work. Sometimes it works, sometimes it doesn't. I have tested different speeds for tapping and I still can't figure out why sometimes it doesn't work. There are people on forums suggesting that running a 144Hz monitor might be an issue and to turn it back to 60Hz. I did that and the problem persisted, so I simply conclude that I am unable to play this game properly. At this point in time there is no hope that this will be fixed so all I can do is warn you. I really wanted to give it a try since it looks like a game I could enjoy but not if something so basic is broken.

A brutally difficult precision platformer where you can only move left and right. Impressive in its simplicity but it is pretty damn hard and I can't say I enjoyed trying it out. Navigation can get a little confusing too.

great game, perfect difficulty curve. very fun to speedrun.

Pretty legit game for just two buttons. Using it to train my kid not to button mash... actual skill and timing and whatnot. good times.

Very cool precision platformer. It's like a mix of Germinal and Celeste Classic.

ótimo jogo de plataforma de precisão, vai fazer você chorar no banho. Recomendo.

I like the level design. The dash controls are kind of a pain sometimes, but I got used to them.

It`s a really challenging game but also it has a unique mechanic. You can only play with to buttons and can only go right or left. Yes you does not have jump button but if you go to the bubbles you will jump. This game is not for everyone because it`s hard. if you have patience you can play.

well designed hardcore platformer WITH ONLY TWO BUTTONSSSS!!111!!

It's physically painful to play on controller, and even with mechanical keyboard the repetitive double-tapping becomes a wearing chore. There's lots to like here, but it's hard for me to get past how uncomfortable the two-button control scheme is. I did turn on 'extra buttons' in the options, but I suspect that's only for controller, as it didn't seem to give me e.g. a key to ballerina leap with. That would have helped.
