Super fun! Every level introduces something new, whether that be a recurring mechanic or a one-off gimmick. Astra has a pretty varied skillset: you have a slide if you want to go fast, and an aerial float if you wanna take it slow. There's collectibles if you're a completionist, and individual level / full game timers if you're a speedrunner.
There's a lot of fun ideas here. Highly recommend if you're a fan of platformers!
