As an endless runner, it's quite simple. Some things I can think of that would keep it more engaging for longer is to have hazards come in bursts. As it is, the only the decision the player has is up or down, and about 50% of the time, not moving is the correct choice. Also, increasing the speed of the gravity flip to go along with faster enemy movement would feel pretty good. Allowing the player to flip gravity midair and having airborne hazards is another idea.

Not sure if it will work well given that you had a mobile implementation, but I would have also liked to see the ability to jump alongside the gravity flip. That would give the player more options to respond to what could be coming ahead if there are hazards on both sides

I liked the sneaky spike. Gave me "I Wanna Be the Guy" vibes

Beautiful game! I really want to get addicted to this, but the red spikes get so unmotivating :D i already have some strategy but sumetimes it just feels like luck to survive or not. maybe if they would jump a little bit earlier? thanks for the great submisson!

I'd just say it could use a difficulty ramp, right now I feel the only challenge is learning the timing of the spikes and after that it's easy to go on forever. Other than that, it's pretty fun!

Felt like the developer read my brain like a book the first time one of the triangles jumped WITH me!! Simple control scheme, great visual design, and fun to play! Awesome stuff!

Good game the first few minutes but a really long one after you noticed the animation indacting that a spike is going to change side.

made it to 307 (was like 6min) the scroll speed should really speed up after a bit and with that simple change your game is going to get a lot more interesting.

Add more obstacle, a going to menu after a death button, and speed up the game over time and it will be a good mobile game.

I like the vibe) 

The thing that bothers me is that I am losing speed after gravity change. But overall it's a good experience. 
I also like that small hint of which of the obstacles is about to fall (up/down). It's very cool. It's easy to miss but at the same time - it's really clear and you have time to react.

At first I thought the game was trolling me. On my first attempt cone flipped with me and I lost. On the second I didn't flip and it didn't either so I died. On the third I just flipped to the opposite side as soon as I saw where cone is located but did not notice that jellyfish thingie flying at me. Solid execution but the concept of flipping gravity is not very original.

not lazy at all.

Like others have mentioned, the amount the ball slows down feels a bit jarring, it detracts from that feeling of fluid motion that makes endless runners satisfying. Aside from that the game looks and sounds great, with plenty of subtle little touches that make it feel nice and juicy.

Simple yet fun mechanic, those triangles are mean let me tell you!

The music was nice, giving Tetrisphere vibes.

On presentation: It’s a simple game and your actions have reasonable feedback. I actually think they may have gone a bit too far: the slowdown when you jump is a bit overextended to the point of being jarring. Moreover, your description promises a minimalist pixel art style, yet no two elements have the same pixel size. The parallax backgrounds are a nice touch, but they don’t quite cycle cleanly; occasionally there are visible jumps. All of these are little things, but taken together they detract from having a good, cohesive experience. I like that the traffic cone enemy gives an anticipation as to what it’s going to do, and you give plenty of time to react to everything.

On gameplay: I reached a score of 300 before letting go of the controls and letting the run end. I mentioned earlier how there’s plenty of anticipation and room to react. On the flip side, this means there is no challenge in the game, and after a couple hundred points rack up it’s hard to stay engaged. It’s hard to overcome that in an endless runner, but one approach might be to slowly dole out new kinds of hazards, or to have any kind of non-flat difficulty curve.

On the limitation: You certainly used it, the gameplay elements are constantly in motion.

Fun game! I liked the effects and the gameplay was solid. One criticism is that the slowdown when you flip gravity makes the controls feel a bit clunky, but otherwise it was a good game. :)

Nice! I wish there were some more enemies, but the triangle guy was actually pretty tricky lol. Nice music too

This is a neat game! I have to say I don't really like the way the ball slows whenever you switch gravity, it makes feels a little clunky and makes it less satisfying to dodge obstacles. Otherwise, I liked it, though! The graphics are really neat - I liked the colors and the starting transition!
