This was fun. I like the aesthetic -- the font, the game sprites, and the color palette all appeared to work well together. The core gameplay loop feels like Flappy Bird, but nothing wrong with that if your goal is implementing mechanics rather than producing something original. I was a bit confused when my flower projectiles started shooting to the pipes underneath me instead of above me, but once I tried to figure out what the up arrow meant on the UI, I figured out the three-jump limit and how that worked.
A couple of notes to improve this project: fix the pipes that spawn overlapping each other, and the '5' in the font is a bit hard to read, could be mistaken for a '6'. Overall, a clean build and gameplay loop that works without any noticeable bugs. Thank you for making this playable in the browser as well. The highest score I was able to get to before I quit was 37.
