cleanup everything for consistency and quality

[dromzeh]

theres a lot of inconsistencies within component/function names, variables etc [e.g in some places we have asset which can easily be confused with an asset item where a name like category would make more sense]

clean code is a must and the state of next definitely isn't that
can probably create some hooks e.g useGameData helpers and good error handling

i'll get this done asap
