Hi, thanks for trying out my game! Sorry you're having issues. Your suggestions are very helpful. I hope I can provide some clarity if you decide to try the game again.
Most of the important helper spheres are right near the starting point of the game. Basically, they'll tell you that a ghost appears at night and chases you and kills you with one touch, but if you collect the sun tokens scattered around, you'll get more sunlight and prevent the ghost from appearing. The amount of sunlight is indicated in the top left of the screen with the number by the sun icon. If it reaches below 10, the sun goes down and the ghost shows up.
If you have at least five crystals, you can fight back against the ghost when he finally does appear. The #/8 number in the top left corner next to the blue diamond shape shows you how many you've collected so far. Collecting all eight crystals is optional and they can be collected in any order.
Yes, the flame you can touch and your player will immediately pick it up. However, a timer will appear, indicating how much time you have before the flame blows out and returns to its original position. If you are able to carry the flame to a candle on time, a crystal will spawn directly above the candle.
The areas where the yellow bubbles are rising up, there are flowers on the ground in those areas. Walking across those will help you move faster for a short time. Some of these are needed for one of the flame/candle puzzles.
The timing of the switching platforms can be tricky. In some areas, it's best to time a jump towards a block right before it appears. The really tall area with the switching platforms is probably the hardest crystal to get, in my opinion.
Here's a hint, one of the crystals is hidden in one of the more dense collection of trees. Also, there's no crystal by the little neighborhood of houses. That area is pretty much there for stocking up on sun tokens.
Thanks again for playing and I appreciate the helpful feedback!
