Yeah the current design is using floats (decimals) for lots of things and that means it is very sensitive to particular positions etc. which means as a player after you solve the puzzle conceptually (ie. you work out what you need to do), you still have to experiment with the meticulous positioning of things to get the particular area that works out. So it favors a playstyle of lots of retries and experimentation, but i think with more dev time i could find a way to quantize the solution space better so it's not so finicky.
If you really get stuck and you're positive you have the right solution, but its frustrating to find the "right" position, you can use the menu to go into edit mode and just remove some elements so you trivially solve it to see the next puzzles.
