Alright, I'm going to point out all the problems I see.
Level 1 (tutorial): Mistakes in the text:
1. "Welcome! Use left and right arrows (or W and D) to move left and right. Proceed to the right."
-The 'W' key makes you jump higher, it does not make you move left, that is the 'A' key
-You do not need the "or" in the parenthesis; it is not needed at all.
-This one isn't need but just personal preference I guess, when it says "Welcome!" I think: Welcome to what? So once you have the name of the game, you should put "Welcome to __!" and then maybe something catchy proceeding that.
2. "You can use the up and down arrows (or W and S) to raise or lower your bounce."
-Again "or" is not needed
-When I first read this I thought if I pressed W it would change the level of my bounce until I pressed S to lower it back down. I didn't realize you had to hold it down, so maybe put "Hold down the up or down arrows..."
3. "This is a bonus star. They are not necessary to finish the elvel, but they do award bonus points."
-Obvious spelling error: change "elvel" to "level"
Overall problems with Level 1 (tutorial):
-You can die in the tutorial?
-If you miss the first blue star, and you get to the end; you can't go back up.
-Just personal preference again, your choice on this one, I think the tutorial level should be called level 0, instead of 1. Since it's not really a full out level. It's up to you on that though.
Level 2 (Just a Taste):
No real problems with this one, except for how short it is, I hope they get longer as the game progresses.
Level 3 (Fun With Warps): Mistakes in the text:
1. "These will waro you to other places!"
-Obvious spelling mistake: change "waro" to "warp"
Level design for Level 3 (Fun With Warps):
-When you first get out of that box thing, you seem to be trapped by two teleporters on both sides, in which you have to jump low underneath them. That's a cool idea for an obstacle but, when you go to them it only leads you to a blue star. That doesn't seem right to me, so even if you don't make it under you still get part of the objective. What you should do is make those lead back into the box that you start in. Then make other teleporters after the blue stars on the bottom level.
-If you choose the left teleporter, then you can simply go to the top of the staircase thing and fall down to get the other blue star, completely voiding the purpose of the right teleporter.
-Pretty short, once again.
Overall problems with the game:
-When looking for blue/red stars, the counter should not start at, for example, 2/2; it should start at 0/2 and work your way up. After you beat the level it counts up the amount of red and blue stars you found, and it says, for example, 2/2; meaning you found all of the stars in that level. So it doesn't make sense to do it two different ways. You see what I mean?
-Colors would be nice, unless you are going for a full black and white outlook.
I enjoyed how the ball moves around, but you need to work on making the levels.
I liked how you changed the speed of the score, that was a nice touch.
Sorry for criticizing you this hard, but it's only to help you.
Keep it up!
