For some reason people keep asking this. Ok, this is a web game, you will be able to play it in any device with a web browser that can run Flash. A mouse is highly recommended since it will be handy for hovering over game elements.
In the future we might consider switching to other technologies more mobile friendly, but right now it is not affordable with the resources at hand.

We are using a "ransom" model in which we will "free" new chapters when we have the funds to do so. These funds will come from donations, selling extra content (OST, developer commented chapters, etc), advertising, merchandise or whatever comes out handy that will not ruin the game experience. You won't have to pay again if you don't want to. You can always help by telling others about the game which will indirectly make the game more profitable.

Absolutly not. We are against P2W (pay to win) games which are bad Free2Play games that make the player farm his way through the game. The game can be played completely for free, and this points, or coins, will only have value in the community and extended features. They are not used to buy ingame items.

We will ask for real money when it comes to fund new chapters, but you are always free to pay. When the chapter is released everybody will play the same game.
