An easy way to implement a save feature is to just have an export function that spits out some text, and then taking the text in the same format and parsing the data. You could do some encoding and decoding to prevent people from editing it easily. (ex. snowflakes, etc => SNOWFLAKES,OTHER1,OTHER2)
Apparently launching your zombie horizontally makes you go much farther... Could there be some camera scrolling when it goes near the top of the screen?
The optimum angle is something like 60 degrees, instead of the 45 degrees you might expect. There is some vertical scrolling but I had to keep the ceiling quite low and so I adjusted the cannon accordingly.
thanks Duuude!!! yes, the gameplay is rather straightforward and simple, but I'm updating almost daily adding new stuff, keep your eyes on it. About the music, I'm sure Jesus (the guy that made the song for the game) will be thrilled to know about this :D

It's awesome to read this Duuude :) thank you a lot for the support... yeah, most people don't realize the work behind the development, but I decided long ago that I would tackle even the most hateful comments politely and with positivity, I try not let those affect my will to keep developing. Even if I got 99 negative reviews, 1 like yours can save my day, thank you :)
VERY annoying and almost unplayable with a trackpad, but that is to be expected with games like this one. Besides that, it runs smoothly and looks pretty fun. Great job!!!
Just so the developer knows: the click damage displayed on the upgrade button shows the damage from the last level if you upgrade it and not the current amount.
Don't get discouraged by other people's bad reviews. Games like this are hard to create, and much harder to get good review on. Just keep on trying and you will get there :)
