Hello ARCA1, thank you for buying the game! Unfortunately you have to pay for new episodes and if you ask why, let me try to enlighten you with a little information:
-it takes serious amounts of time to prepare each scene, the most time consuming part. I don't use cheap blurring techniques in my renders so everything in the scene has to look good!(with blurring, you can simply cover mistakes easily)
-An example of rendering work: it took more or less 20 days, 20 full days of rendering time, 24hrsx20 days to render the images for episode 3. Episode 3 contains 260images. Quality comes with a price...
-I change the outfits of the characters atleast 2 or 3 times in a single episode to keep things fresh and unordinary which is another time consuming process and I always use real 3d environtments, not some flat background picture.
-the game is currently priced $2 for episode 3 and unfortunately with the taxes, payment fees, etc I can barely earn 1$ per sale. Even though that doesn't make much of an income, I didn't want to change the price for episode 3 and the price for episode 4 which includes almost 500 renders will definitely be higher...
My sincere regards
Thank you
