My first shots at puzzle-making:

[LilFaery]

raboziv  solution: zipegip
zymyfis  solution: zuvodyk
vibunoz  solution: cibehel
gicysuz  solution: zydylat
sydivev solution: dogagiv

[20eight]

here's my solution to raboziv:hukadyp

[jnz]

My solution for Generic Pit (raboziv): catidux.  Took me a minute to figure out how to trigger the door key with no packers or unpackers available. 

[Lazyone]

Here is my solution Jydusub

[Shamil]

solution without the bulldozer : nolyror

[LilFaery]

A couple more:  zymyfis and vibunoz

[Lazyone]

for vibunoz my solution is sexidid

For zymyfis my solution is cafacap it takes forever but gets the job done.

[LilFaery]

Another: gicysuz

[Lazyone]

For gicysuz here is my solution bokyzub

Nice level

[Handi]

Here's my solution to vibunoz : tapasut
Nice level! Actually, i had almost exactly the same idea recently... I just haven't found the time to make the level.

[Djonn]

My solution to gicysuz:pobovab. I liked this.

[adept]

this is how I counted the crates xynidav.  Just watching how you designed the level to produce the right number of crates was interesting.  Good job on all these puzzles.

[jnz]

My solution for ThreeCs (zymyfis): gasodak (even slower than Lazyone's)
And for Synchronization (vibunoz): gyvofuh (surprisingly simple for such a complex starting machine)

[Lazyone]

Adept  your solution doesn't solve for 2 or 0 xynidav

On zymyfis I spent a long time on first attempt (doxygel).  For some reason I thought that F + F would = C.  Of course I didn't realize until I was almost done.  It's worth checking out anyway (even though it takes a really long time).

Then I came up with this xybunek, which I see now that I look is basically the same as Lazyone's.
