The gameplay and level design was quite good.
However, the art style and graphics (i know it's retro game, but still) would need a bit work.
Can you plz add level choose menu to this game ? So i can revisit levels, and you can lock eack with its own code, as was the standard back then.
It's interesting that i came across this game as i said that most today's Itch 3D platformers are garbage, and this one started boring, but it got really fun in the underground area, and it flew nicely from there.
