Flappy bird is always a good learning project

• Innovation – Literally just flappy bird, but it works well :D  Perhaps you can add 1 more mechanic next, like... Flappy bird, but the bird can shoot!
• Fun – The controls feel correct for flappy bird, good job.
• Graphics – Literally flappy bird haha.  Perhaps you could find or make some 50s animation style assets and particles?
• Audio – just music~  I would add a flapping sound every time you click, death sound, etc.
• Polish – A great learning experience game!

Great job completing a full game loop!  Please check out my game if you like Metroidvanias or platformers :D
