Good stuff:

The particles are very nicely done, the explosions and egg effects and all
Sounds are nice altho a bit loud
Fits Easter theme perfectly

Bad stuff:
Seems like player control is pretty less, like you can only aim and shoot and even that doesn't require too much precision/effort/attention
A bit too fast, like too much stuff happens too fast to process
Color contrast is pretty less, so hard to really distinguish stuff specially when it's coming down so fast

Now this is a particle overdose. Just bits and bobs all over the place all the time. It can sometimes be hard to tell exactly what's going on, but it also looks colorful and crazy, and I love it when things look colorful and crazy! 

Bubble good

First of all next time zip your game so that there is a main folder, (Eggstravaganza/main.py).. Also it's a really weird resolution.

It's a really cool entry that fits all the themes nicely. But wow, does it really throw you off the deep end immediately lol. A little tone down would make this enjoyable probably.

forgot to tell you but it's too hard. ease it up!

The game is fun, and looks utterly beautiful I liked the particles

your web build seems to run faster than it should, I created a new one from source and it seems to work a bit better, just made small adjustments to the main file,  are you using version 0.7.1 of pygbag?

the changes I made:

added async before def run() on line 225

uncommented the await sleep line 257

changed line 263 to asyncio.run(game.run())
