Hi, nice game but i need to point out something : you need to adjust the way you award the gold star : there are many ways to finish a level, but if you use a "one way door" instead of a "gold bag", you get awarded a silver instead of gold, and the other way around in another level. That causes the player to waste time on thinking how he can switch gold bags with one way doors to achieve gold star, which depends on no logical thinking :)
nice game, simple gameplay with addictiveness. spent a few days playing it already :) but if you ever think of making a sequel, you will have to spend a lot more time on developing ai :) i congragulate you and wish you luck on your following endeavours (i've been waiting so long to use this word in a sentence :p)
