I think there is a solid core here, but the goat is a little too slippery at times to really feel like you're making precise jumps. Also, dying in later levels sending you back to the first level makes it a bit more frustrating than it could have been otherwise when learning how new enemies work. I think you need more than one health to start out with so you can make mistakes with the first level enemies so it doesn't feel like you suddenly clip the wrong part of one and die, and then maybe a drop shadow beneath the Goat so you know where he's going to land.
There's a solid little platformer here but it's definitely a little too frustrating to wrap your head around the essentials of how to get the game to work. On the other hand I wanna speedrun it because I'm weird but I think the threat of the cloud makes learning the game as a newcomer extremely frustrating before you get that point of mastery. Like, first time playing it I died to that yellow bird in world 2 because I thought I just have to jump on it like the red ones, died and whoops back to level 1 and just closed it out of annoyance.
