Level 24 is a real challenge, but it can be solved with logic. Takes a while to see the solution because there is none like it in any other puzzle. When you see it you'll smack yourself.
i love these point and click adventure, but this is bad. You run around clicking every icon on every single item to get any where. Even with the walk through the game is hard. 2/5 for the visual, game play is worthless.
Quickly upgrade gun damage, reload (so you don't run out of rounds, 1 point should be enough for the first few levels) and more point for each balloon kill. To get the first boss you need maxed out winged bombs, and also the freeze building. Good luck.
