problems... I mean, a bit feedback

[670839245]

1st, the character moves SO fast that I may not control him very well(level1 near the beginning, clouds with coins)
2nd, the menu "help" in the designer was broken.
3rd(this time a question), what can COINS do? just collect for fun?? And how many small coins do a big coin worth?

4th(NEW!!),old levels CANNOT be used in the new game.

I've discovered the 2nd problem too! I wonder how much help it offers.

If your game is set to 60 fps, try lowering it to 30 fps. Just go to options, and then quality. If not, then there's nothing you can do about it. He does move fast, but it shouldn't be so fast that you can't control him.

3rd(this time a question), what can COINS do? just collect for fun?? And how many small coins do a big coin worth?

I'm assuming by coins you mean the triangle things, which are strangely called Squares. Since the game is in beta, squares have no value, but hopefully they will later on in development.

4th(NEW!!),old levels CANNOT be used in the new game.

To an extent, they can, but a lot of things were changed, so it really depends on the level. Tiles should load correctly, but you'll more than likely have to make edits with any items or any effects, since those were changed.

First of all. Post it in the bugs thread and the feedback thread (if we have one)

1st, the character moves SO fast that I may not control him very well(level1 near the beginning, clouds with coins)

I have no idea how that's happening, that's your problem

2nd, the menu "help" in the designer was broken.

We have already established this a bunch of times. It is a bug and it will be fixed.

3rd(this time a question), what can COINS do? just collect for fun?? And how many small coins do a big coin worth?

They will have an OnCollect property, or trigger, in the next update. (if you even know what properties/triggers are)

4th(NEW!!),old levels CANNOT be used in the new game.

This isn't new. It's not true either. Some things are broken, but you can still play the levels, just need to fix a few things.
Runouw said he's adding old level compatibility soon anyways.
