If you are into Sonic style games then na_th_ans latest NES homebrew project Espitene is clearly for you. The game has 12 regular stages and 6 boss stages. Collect emeralds and rings, avoid enemies and take care of the big bad ones.
Right now this game is in beta stage, so count with a few irregularities here and there but overall its a solid upcoming Mojon Twins production, created with their very own AGNES engine.
