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!
