Ratings and reviews

hey it's me again I complained about the the second version of this game. I was just freaked out. because of the sound effects and I couldn't get off the game. the game I enjoy your games especially this one. but please. don't ever make things like that. thank you for making this amazing game!

The game was fun until I faced "hardest" levels. Many of them are way more luck based than skill based. The game became extremely frustrating. Luck shouldn't be the meaning of harder levels. Response to dev: I don't think someone with talent will pass without needing extreme luck too. this is my complaint. Please listen to it and try to understand. By the way, I consider myself talented in platformers. For example, I really love Super Meat Boy, and I finished the game.

For the initial difficulty, the game is "fun" and "challenging", with the last few levels needing some luck... But then you reach the "hardest" difficulty, and it goes from a 80% skill, 20% luck to 20% skill, 80% luck within a few levels, witha. Lot of moving platforms and obstacles where a difference of 1px can mean missing a platform or grazing it, making the following jumps impossible to make. Furthermore... Why do i have to wait so long between deaths? 1s playing to 2s loading is horrible
