Very fun
A great game, nice graphics, fairly easy to handle (usually) and pretty fun in general.
The biggest problems I had were with the jump mechanics. I felt like the jumping wasn't as responsive as it could have been--both in terms of when you jump and how you move through the air. On one level, the one where you have to jump over the pit of spikes, bounce off the wall, and then use your bird to reach the opposite crumbling wall and bounce off of that, I died a lot because it was hard to control my direction after rebounding. The last level I played, the first one with crumbling columns, I died 3 times in a row because I simply wouldn't jump, even though I pressed the key. I'm pretty sure my timing was right, making me think it's some kind of glitch. Very frustrating.
I also discovered something I'm sure is a glitch; if you hit the base of the crumbling columns, so they collapse on top of you, and then retry the level, the column will crumble at the start, making the level undoable. I ended up failing the level 2 times because of that. Ultimately why I'm writing this review lol
