FYI, yes of course they were made recently and itch.io only accept rating/comment via their account only. Most of them(most of them were never heard of itch.io though) may be from my office/friends whom I shared my sumbission today. If you feel this is kind of cheating then(I don't know is there any way) substract those rating from my game. Also my account is linked to my real Twitter account. I don't think it's crime to share my game between my friends. I don't think me as a great or better game developer. I make software for living and make games for fun. I submitted my entry to participate not to win the price. If I'm selected I will graciously reject the prize.
