Maybe I'll rename this and add another levels, but for now it will say only how to solve "finding curves" level

Detailed:
1. Go right until 22 Fuel left
2. Set power to max, make your Traectory triangle touch middle up line from left (it's 4 ← buttons from the top center position, when Traectory triangle cross the middle up line)
(arrow show the middle up line)
3. Click ← for 32 times and ↓ for 32 times and shoot
4.Go left until 24 Fuel left
5. Set Traectory triangle cross ↗ line
(arrow show the ↗ line)
click ↑ for 7 times (or ↓ for 25 times, if you set power to max) and shoot
6. Go rightuntil no fuel left.
7.... well, I jusr random shooted with same power and got it. Write exact angle if you'll take it too

Traectory triangle Δ – this is that thing that moving while you click arrows buttons while aiming. Tell me if this thing have a name.
First I write about angle, next about power
Lines means one of thouse 8 lines you see when aiming.
# ↑ mean make your Δ should touch line: from left if # is negative (ex. -7), from right if it's possitive (ex. 3)
If |↑ if means set Δ from left to line, ↑| means from right. 4 |↑ means Δ crossing ↑
after separator "," there wrotten how many ↓ clicks from max power position you should make
#F → – mean that you should go right (if →) or left (if ←) # fuel steps (if # is positive) or untill # fuel left (if negative)

You can see an example in Finding Curves walktrough. All next walktroughtes will be with обозначениями.
Why I'm write English? Because it more worldwide, yeah I'm too lasy to translate some Russian words and I'm too lasy to write Russian guide to, but I'm probably do last sometime
