1. you need food to at least let us live without dying of hunger.
2. Light will not affect the spawners unless they are surrounding the adjacent square.
3. the pictures are not setting off the spawners explosives and i have seen that the ending one are not even set up!!! either make the area that they go into bigger or set them up so that they actually set off! in other words TEST your work. it really did not look like it was TESTED if i had to break your map to continue after shooting ever single picture!!.
other than that, i would love to see this map actually be finished. has a nice mechanic, just needs to be tested and fool proof before you set out a beta (kinda frustrating when an idea doesn't work).
