You made the game easier? I fear the state of the game in its first iteration lol this is pretty difficult. Its very hard to see the pipes since the camera is so close to the bird, it is very fun though

Pretty fun but it's a bit hard to see how close you are to the pipes

This is a pretty fun idea. Looks good, sounds good, very easy to understand.

I echo what others have said, the movement is too stiff and the perspective is difficult to work with. I'd recommend having a bit of acceleration to the birds movements to smooth out the motion and either move the camera back, shrink the bird, or have some kind of outline to better see the pipes.

It bugs me that hitting the left/right arrow after I've moved all the way to one side triggers a jump. At first I didn't understand that's what was happening as I was jumping directly into the ceiling and losing.

Getting a point and then immediately moving left or right should have more forgiveness - maybe disable the colliders once you get a point?

Thanks for your entry!

Things that I think are good:

• SFX balance is on point, sounds are familiar and coherent, feels like a part of Flappy Bird multiverse haha.
• Graphics are stylized and good, like the blockiness and color palette.
• Controls feel appropriate and simple, as they should be. They are also communicated properly. 
• Good UI that keep you focused on the core gameplay.
• Easy to replay.

Things that in my opinion could use some polish:

• UX stuff: bird moves very quickly and it is hard to time your "flaps", as it is hard to understand the 3D space from chosen perspective. As other commenters suggest — making the bird contain less space on the game screen can improve the feeling of movement and make it easier to aim. Also you can try and tweak the amplitude of the bird's vertical movement. Other rows of pillars distract from the main goal, I would suggest to use them more intensively from the start to "sell" the 3D aspect of the game better.
• Feels very hard to get scores. One wrongly timed SPACE button can ruin the run, no place for a mistake and I don't feel in control while playing. As if the placement of the pillars is more responsible for my score than skill. I had to grind for every point but could make it only to 11 pts.
• Game lacks some background music, which can support the experience.
• I would try to make something with overall visuals — as I said the stylization is good, but the same empty background with checkers make it feel a little bit repeatative. 

Overall:

Nice concept and good implementation of the core. With some polish and attention to some UX problems can be even more fun and captivating experience. Good entry!

I like the idea of changing columns it does add a dimension to the game!

I think the visibility is hard since the bird is massive and you really have to guess where the gap is that you can enter. Maybe moving the camera a bit back or reducing the bird's size would help? or maybe even some sort of transparent thing or outlining the pipes even though the bird so you see where they

Also, it'd be nice to move around with AD as well as arrows.

Besides those the gameplay, sound, and art are quite nice.

This is a fun 3d version for flappy bird, it gives you a sense of achievement when you reach more and more points (I stopped at 25 because i failed a lot but will keep playing to go over 88 haha) now, a few points to give that i think will make the game much better, and people won't stop playing. 

* A pause menu, will help a lot, sometimes you need to pause for a second or even if you need to change something, which leads me to another suggestion.

*Options menu with at least sound volume and also the possibility to change from fullscreen to windowed mode, It's something very useful for people to play better

*Music, music and more music. This game with a fun beat on the background would keep people dancing and flapping all over.

*Controls on screen, even thou you have them in your page, it's a great addition just to have them there. Or even in the pause menu to avoid having more stuff on the main hud.

Besides this recommendations, the game is overall fun and i can see streamers trying to reach the highscore a lot! Great work!
