This is a fun and creative game. The art is nice, and the music is really fitting. I liked the controls, and the fact that two players could play, though I didn’t have that opportunity. I would have loved controller support, because this game would be a great couch + dpad game.
With the vine/player moving down, and the birds moving straight, it gave the impression that the birds were outpacing the vine’s growth upwards. This was particularly noticeable during boosted growth. Obviously levels moving is a common behind the scenes game mechanic, but this broke the illusion and was a bit disorienting.
I felt that the upgrades were not very impactful for how frequently they came. 2400m was also a bit too long for a game jam. I liked the game, but there are many others to play :)
All in all, I think this is a really great entry. It’s unique, it’s fun, and it’s definitely replayable. I love the idea of more local couch games with friends in the world, but that requires controller support!
Well done!
