I didnt know this was your first game, so great job!! I'm not going to delve much because other ppl said it already. There is a lot of room for improvement but you have talent, the design of the four room and the switches and one of them having multiple switches was a good puzzle IMO. You need to think of making a more cohesive story , but it was...ok.
Also, you had me on "I see, humans are still stupid." XD XD XD
