Hello! As a fellow indie developer, I completely understand your reasoning for this decision. At this time, the price mentioned is too much even for me and my team. Unfortunately, this is completely out of my control and there is little I can do to combat it unless/until we made a standalone version.
If you want my two cents however, I personally believe that the 80$ a month is reasonable expense for games that are performing well enough to justify porting to multiple consoles. This especially in consideration of the fact that RPGMaker doesn't offer console ports at all, and also when compared to Unity's 187$ per month, per user "Pro" license that is required for console ports, ouch! Additionally, the amount of work me and my team pour into our games for just the PC version is immense, I can't imagine opening up to several other consoles without at least doubling the team size.
Regardless, I'm glad you were at least satisfied with the design of my product, and I hope you can reconsider using MonMae again in the future. Thank you very much for your input!
