Alright, here's one: https://paulsgames.itch.io/ostarkdidi
Questions:
1) Are there are levels that were too hard or frustrating?
2) How far did you get until you were bored?
3) What is the main thing you would you add to make it more attractive?

I played the first 6 levels. The only frustrating thing is that this game seems to be designed for 2 players. It's hard to control both birds at once. Also, I think that both birds are required to be on screen at the same time, that should be explained. One of the levels (the one with two "floors" with one bird on each floor, and they have to both move to the right) is frustrating until I figured out that constraint.
To make it more attractive, pick a certain aesthetic and stick to it. It looks realistic but the rigid pattern of blocks all stacked neatly on top of each other to form the walls looks unrealistic. Make it more cartoonish and I think it would be better.
Thanks for the detailed feedback, awesome! I recognize the things you point out. Indeed, the game is mainly designed for two players, only later I added single player mode. I also agree on the tile look. The game has come a long way from its game jam roots, but the tiles are still as they were made in the first weekend. That should be a priority.
