*sigh* Fine, I'll do something helpful around here for a change. *downloads map*
Timing:
BPM: 130
Offset: 370
Your timing was off, hence your problem. However, your rhythm was way off. I would just remap at this point. Here, let me give you basic rhythm lessons:
1. You see the white ticks? They go to the beat. The basis of any rhythm should be the beat.
2. See those long white ticks? Almost always have either a hit circle or the start of a slider on those. These are the starts of a measure and are extremely strong.
3. There are 3 shorter white ticks in between each long white tick, right? Well, the middle one is also important. For Easy and Normal difficulties, you typically want to have a base rhythm of a hit circle/slider start on the long white ticks and the middle white ticks. Easy, right? But then you can (and want to) mix it up a bit:
a) For important transitions, you can skip the middle tick and have a hit circle/slider start on the white tick right before the long white tick instead. It's tricky for newer players, despite the fact that you have more time to hit the hit circle. It's a mix-up of sorts and is kinda hard to explain why it works.
b) Placing hit circles and slider ends on the other white ticks during specific parts helps. Experiment and you should get the hang of it.
Once you get the hang of making easy difficulties, pay attention to the rhythms the instruments use. Map close to those for harder difficulties. If you want to make a really hard map, then simply choose a song with crazy instruments that let you do some pretty crazy mapping. Similarly, a song with more relaxed instruments (ex. no 1/4s at all) are a good choice for easier maps.
There, that should get you started on the right track. Oh, and do adjust the slider velocity. Since you want to use Distance Snap quite a bit when you start mapping, having a slider velocity that lets you get the spacing you want without really weird DS multipliers like 0.4x or 1.8x is very important because you want a smooth transition from hit circles to sliders.
There, happy? D:
