In version 1.0.3 we've added 3 save slots for each level. Now you can have and quickly switch between different solutions for the same puzzle.
Update v1.0.2
We've been busy updating the game over the past few days. Here is a list of the changes that we'll call version 1.0.2:
fixed a bug in the behaviour of Type 1 switches in some cases(thanks to reesylou for reporting it)
added a key for clearing residual beams("C")
changed the optimization challenge for level 37(First 5 last 5) to avoid an easy brute force solution
added optimization challenges to levels that didn't have any(thanks to Innocentive)
changed the input in level 19(RGB) to avoid using the same solution as in level 4(Beam splitting)
other minor improvements here and there
If you are stuck somewhere and need some tips, want to see a highly optimized solution or maybe a different approach to solving a particular level check out Innocentive's great guide.
