trust me its not hackproof, except you put in formulas for changing variables, so they don't relate to their use anymore
except you mean hackproof as in, you cant rightclick forward...
pro: You have quite a solid engine there, except that for my taste its quite too random how far you get, it never depends on your timing skills
con: grafics, music is super annoying and doesn't loop properly, also no off button
if you spend a little more time on it and bring in more creativity and innovation then it could become good
