I'm not a person who actively does runs for records, but I do like to find shortcuts/skips in games. I found this game a few months ago and decided to play around with it. In that time, I have noticed two strategies i've used that I have not seen in any runs on the leaderboard. Unfortunately, I am unable to show videos or photos of these strats, so I will try my best to describe them.

-Level 16- This level requires you to melt an ice block on the right into the path of a green blob. Jump over him to go to the very left. And use the top platforms to touch both bonfires.

But remember that lone ice block you melt to reach the roof? Well, I found that it is possible to jump around it and stand on top of it. With this, you can do another jump to reach the right-most bonfire. Then jump over and touch the left one. This skips having to circle the area and avoids the green blob entirely.

-Level 26- This is the level with disappearing purple blocks acting as stepping stones to get to the bonfire. All runs just jump one platform at a time, which take 6 cycles (Cycles being when the green blob presses a button).

However, if you jump on the very edge of the first platform, you are will have enough reach to reach the third platform right before it disappears. Jumping as soon as you land on it will allow you to survive. This allows you to beat the level in only 4 cycles. However, this trick is very dangerous and can kill your run right at the end.
