Neat, I looked at the screenshots and said 'HEY LOOKS LIKE A LEMMINGS CLONE' and then I looked at your text which told me 'HEY THIS IS A LEMMINGS CLONE' so I am super proud of myself and will give you hugs if you finish it.
Just gotta say, this game plays AWESOME!! One of the best click games I've played in a while. About time someone made something that is (probably) inspired by the flash 'Hapland' games..! This game is definitely one to look out for.
I really enjoyed the demo for this game. Simple but fairly original. I don't think it's a lemmings clone at all, it's just similar in that the main protagonist isn't directly controlled by the player. Keep up the good work, I look forward to the final version of this game.
Sorry to hear about your loss (the computer crash thing!), i've had this problem in the past and had to re-do lots of work - very irritating!! Hope it all works out well anyways, can't wait to play
