Instead of simply rating games, I want you to play the game and really think about what you like and dislike.
A good way to do this is to make 2 lists: one with things you like and one with thing that could've been better and how you'd like it to be instead. Next, add these lists to a comment for the game developer. For example:
Pros
- The music was excellent and fit the game well.
- The rewind mechanic was well implemented, I especially liked how objects would move back to their original position.
Cons
- The jumping felt a bit floaty. Try to make the character move up and down a bit faster.
- There's no game over screen for when you fall down. Adding this with a button prompt to restart the level would make the game flow even better.
As you can tell, this is far more valuable than simply leaving a rating and be done with it. The creator actually gets a chance to improve the game and his/her next games.
I try to give valuable feedback as often as I can, and I'd like to ask the same of you so we can all improve together and make awesome games!
Thanks!
