Thanks for your feedback! The same coloured lasers were actually made that way so it would be kinda chaotic to manage the reflections and I think adding a zoom would definitely help see the reflections easier. And yep I will definitely add a zoom / minimap feature in a future update since everyone's feedback is add this feature. I did intend to introduce different colour for different endpoints so like all green lasers would need to point to the green and all red coloured ones would need to point to the red one.
What a coincidence! The colour addition idea you've mentioned is actually one of the things that my friend had suggested to me to add in my future update for the game!
For the level locking, it's kind of a force of habit for me but I totally agree with you to keep all levels unlocked for the jam in order for people to experience the game fully without being progress locked. I will remember this for future builds. I really appreciate this feedback, it was really helpful! Thanks again!
