I like hearing a sound for each time I collect something (like in Mario). A counter for how many coins I've collected would also help. A restart button would be nice too, I got to the black circle with the red arrow and was stuck there. Keep it up, your showing improvement.
In response to some of your comments: I am not an architect lol. Yes, I made this game. I haven't played pokemon since blue and red came out. I never said it's a truly original game, but when I searched for a similar game to my own I turned up with nothing. I am waiting to hear from Kongregate about badges. If and when the game does get badges, you shouldn't have to play it all over again to get the ones you already earned. I do not provide a tutorial because I wanted players to discover how by themselves. The game gives hints like "Open Doors", "Use Arrow Keys", and X marks the spot. Also, the first few levels are designed to show the mechanics of the doors and are otherwise too easy if you have beaten the game. So learning how to play is part of the puzzle. Remember, this game is in the puzzle category. I've never heard of Konqueror but I'll check it out. Thank you for your comments, critiques, and suggestions. I will keep them all in mind whenever I make a sequel to this game.
