Press the ?-button in top right corner for game-play instructions. The speaker button turns off and on sound effects. The music note turns music on and off. If you like this game (or if think it could use some improvements), be on the look out for the sequel to this game I'm in the process of making right now!
I wrote the music for Operation Koala on MuseScore. I also did all the artwork and coding. Certain sound effects came from Free-sound.org. I hope you enjoy it. By the way, there is a cool boss at the end, so you should totally go through all five levels to get to it. ʕ•ᴥ•ʔ
