OK, I just downloaded and played the game and I got as far as the 2. Dungeon, but then I couldn't go on (I'll explain later why). The game was really nice, because there was something to do (Dungeons). I also liked that there were many features, like ledge jumping and thrusting your sword against walls when charging for a spin attack.
In the first picture there is a staircase behind the HUD-Button with the Feather. I didn't see it when I got there, so I saved and chose 'Last Location'. I started in a cave I had never seen before with two possible ways to go. One leads to the 2. Dungeon, the other one (after more caves) brought me to the cave in the screenshot again, but this time I entered via the 'hidden' staircase. That's how I found out it was there. It should be clearer for the player that there is an exit.
The second picture: That's as far as I could go. When I exited the room through the north exit, nothing would happen. Maybe you haven't built the room north of this one, but maybe not, because when I wanted to leave the room through the south exit it didn't work either, so maybe you just forgot to add those two portals.
Some other things I noticed:
- Some sounds were too loud in comparison to others.
- Always redoing the puzzles when entering the room a second time was annoying, especially longer ones like the puzzle in the second room of the second Dungeon.
- The rupee and key HUD numbers shouldn't be black in my opinion. I'ts often hard to see.
