There was a problem hiding this comment.
Code looks sensible, fix the variable names to up the readability though.

Description
Fix raycasting "pass-through" collision inaccuracies with better modelling.
I started by first principles with the formula and told the clanker to implement, so please review with some grains of salt!
The code before had some unnecessary complexity trying to check which side it was before using the intersection formula, so this is a simpler more direct approach.
There is still epsilon wrangling, in fact it is more in your face than ever, but I couldn't find a way to not have it starting from the vector2s data.
I am very open to other suggestions or alternatives here and happy to move implementation forward!
