I enjoyed the first game Cruel Serenade and while i would like to play your 2nd game it a bit too expensive, and mostly me not liking to puting out my credit card and birth month online
The game really isn't that expensive. And I think it's awesome that the first one is free so that players know what they are paying for before buying it.
And while your concerns are valid about inputting your info. Plenty of people before you have made secure transactions on this site without issue.
If it helps put your mind at ease. The personal info any secure online payment process and method requires helps ensure whoever is using the credit card is the actual card holder and not some identity thief.
Cost comes down to the person obviously. I think it's a reasonable price for what's on offer, but only you can say whether it makes sense as a purchase for you. As for the info, depends what you're concerned with. If it's a privacy issue, I hear you, and that's just one of the unfortunate realities of buying stuff online. I really wish there was an anonymous way of buying stuff digitally (that was actually practical, unlike crypto), like cash, but the powers that be will NEVER let that happen, because they've gotten used to being able to track everyone. If you're just concerned with fraud, there are services that let you make "disposable" cards you can put limits on so there's no chance of unexpected charges. Even without that though, most cards and banks these days are more than willing to assist with fraudulent charges, and you're USUALLY not left holding the back, though your mileage may vary.
