Interesting game, definitely reminds me of flash games I used to play when I was younger haha. I was a bit confused why you could shoot the vines near the end but you couldn't shoot the vine near the beginning and had to use the crane and a box instead? Also if you could keep the music running throughout each scene (rather than replaying it from the beginning each time you go through the elevator) and that would be a lot nicer!
Nice job :)
