Thanks a lot for the feedback! Yes, the intention was to make a PSX feeling. The fire meter is set to froze after you gather all the fire orbs so you shouldn't be worrying about running out of fire but just finding all the potions to craft the orb. Looks like we failed into comunicating that.
Thanks for the tip about the landmarks, will have that in consideration in the future!
We are aware of the performance issues and frame drops, saw them when we ported the game to WebGL and after we uploaded it. Couldn't really find a quick solution but we'll check into that later.
We are happy that you had a good experience!
