Nice work getting a submission in - I did a quick recording of my gameplay in case it's helpful: Crabby Bird by Henry | Cap Recording
I found the game very difficult, getting a high score of 3 😆
You will see when I first started a fresh round, it was quite tricky to land my first hop with the crab. I did get the hang of it, but potentially having the crab horizontally scrolling at the start of the game, with your first click acting as a hop, could be a nicer way to ease the player into the game.
I also had some trouble with the hitboxes on the crab and pipes. On the lose screen it looks like I should have cleared the gap, but it would register as a loss and kick me back to the start.
I still think this is a solid entry - and with a little bit of tweaking would be awesome! Well done overall.
