Thanks so much man!
First off, the saving feature should work fine. How did you close the game? The whole character is saved. Take a look at the "Saves" folder and see if there is a file in there.
Yup, the teleporters don't spawn on spikes anymore.
Yup, I've already thought about other trap types, especially fire traps :)
Torches will be fixed!
Yup, as I've said there isn't much going on with the difficulty variation in the current demo
Doors and Keys sounds good, maybe only for certain dungeon types like Ruins or Pyramids?
I've recently replaced the random overworld chest with actual secrets! So you have to burn bushes, bomb a wall, push away a block, the other ones I won't reveal :)
Yup, the game is not "completable" yet. The "Amulet of Yendor" is still missing. But congrats on beating all dungeons man!
As I've said, your items and equipment are saved. You should not lose it :/ something probably went wrong. If you close the game or exit in the "Settings" Menu, everything is saved for sure
And there's also progression items now! Currently, there are Flippers for the Forest and Climbing Gear for the Mountains :)
Thanks so much for the in-depth feedback!
A new demo will come really soon :)
