Very cool 10/10 made me want to get back into design

too hard :( cannot finish this

@AlExIsAwEsOmE Unforunately there isn't really much i can do in that case. There is a windows 10 feature that may help you out though:
win10 settings>personalization>colors (left sidebar)>high contrast settings (top right corner)>colors filters (left sidebar)
There should be a color filter option for deuteranopia which hopefully will help you. Let me know if this works for you!

I'm partially red-green color-blind :'(

@AlExIsAwEsOmE There is still the same type of indication as before (one of the sides pulses green, indicating the path you should go), there is just a bit less time to do so than the previous two. If you can't see the green pulse, do let me know and i'll look into it

I don't uinderstand how the last portion works. Is there some hint as to which of the four sides of the tunnel will stop working next, or are we just supposed to memorize the order?
