Super well polished little experience, short and very effective. The art is minimalistic but very polished and with fitting sound effects. The absence of a background music is a bit of a downer though, I think a short 8 bit track would improve the game a lot.
The gameplay is what you'd expect from any other game like this, though the seed part is a great spin on things. I just love how well designed that part is, it managed to catch me offguard at certain sections, very clever stuff.
Overall it's nice and polished with clever level design. Congrats!
