i have made Portal in Minecraft with the bow being the Portal Gun. My facility includes 3 test chambers including a boss fight with GLaDos. When using the portal gun shoot one of the two buttons to activate a portal when 2 portals are active walk through. If you have any ideas to make it better please leave it in the comments also if you find any bugs put that in the comments and i will fix it as soon as i can Thank you.

Main problems:
arrows stay on buttons and you will have to wait
for the arrows to come off or take them off.

Update:
fixed some bugs
fixed the elevators( they got cut off they are now working)
