Is it ok to use pre-existing assets from other games when making my first sonic fangame?

Im wanting to make a fangame in the "Sonic Worlds Next" engine, and it would be my first fangame and first ever released game. Is it fine to use tiles and such from other games (example: Mega Man) as long as i give credit? (p.s. i know it wouldnt be legally ok, but is it lazy for a first real shot (the only other games i made are in scratch, and unreleased))

You should be fine, go ahead.
