Save system was added, because in the beginning I wanted the game to be more robust, with unlocks and such. Then it occurred to us, that all this would be pretty hard in two weeks, so we tied unlocks to level goals, but the save system remained.
Nice of you to notice the suppressor animation! My graphics guy tells me that making things shorter ant then longer suddenly is pretty standard technique, but I do agree with you- it looks fun!
