nice job on the game I had some issues getting more then 5 light plants going before they started turning off I probably will be able to do it if I play the game another time now that I know where the gas is at.
I noticed the enemy get larger as time goes on to the point that they are so large they couldn't even hit me not sure if that was intention on the size getting that large or not though made getting around pretty easy though.(that was on the game jam version of the game)
