Cheritz, a Korean company creating female-oriented visual novel / dating sim hybrids, are running a competition + raffle where you can get “random unrevealed/soldout game goods”. The competition can be entered from any country; last day of entry is the 27th.
To enter, you’ll have to buy Dandelion on Steam, play it once, then leave a review on its Steam page. While the price is somewhat steep at $29,99, the novel is voiced and production values are quite high. You can find the full instructions here.
Apart from Dandelion, Cheritz has put their second VN, Nameless, up on Greenlight.
