Don't use fakemeta_util to set health, use fun module.
Use switch statement for menu key check.
Use pcvars.
Cache pcvar values.
Don't use a colorchat function when the function is only used once, the loop is also not needed.

About features, plugin is too static, you could for example put a config file with settings (1 line for HP amount and price ) so users could put as many menu option as they would like).

About public cvar, don't you think it is a bit much for such a plugin ?
