The game is MEANT TO BE REALLY HARD. The game doesn't suck just because you can't beat it. It is not impossible.
The birds add different elements to the game. Not double jumping, not killing anything and not taking your time force you to get good at all aspects of the game. For instance, you need to use dash jumps where a double jump would've been fine, or a critter on a small moving platform now becomes a huge problem if you need to avoid killing it.
The pixel art is beautiful. If it doesn't appeal to you that's fine, but again that doesn't mean the graphics suck.
The lag is truly frustrating, but I believe that's Kongregate's fault, not the game's fault. I've played it elsewhere and it's been lag-free.
5/5
