Congrats on the Aldorlea release, Starmage! I gotta admit, I've seen your game pop up a *bunch* of times all over the place, and I've kept meaning to say something to you and kept forgetting :/ I love the artstyle, esp the cover art!
Also I really would recommend looking into implementing a mouse control system (among other QoL things, like easy fullscreen access, exit game buttons and easier difficulties if you don't have any already) if you can--a lotta folks on Aldorlea play *much* more casually than Steam users, in my experience.
That's an unusual sequence of events. Usually, a developer would publish the game first on Aldorlea as a timed exclusive, which is the only - if at all - reason to buy something on this platform where everything is overpriced. Your game is available since the end of August last year on Steam for a reasonable price, but on Aldorlea it costs four times as much.
It's not nearly as uncommon as you'd think, though. A lot of us end up releasing on Aldorlea after Steam just because we weren't aware that Aldorlea even existed beforehand. I have quite a few commercial games, and to this day I've only managed to release 1 as a timed exclusive (all the others released on Steam first).
I won't name the exact cut Aldorlea takes--but combining Indinera's share of the profits and the fee from BMTMicro (the payment processor), it's essentially
double what Steam takes. That's part of why games there cost so much more.
Another part is that, honestly, the folks there are just willing to pay more. I could be wrong, but I'm pretty sure the Aldorlea audience skews much older (middle-late aged), and though a good number of them will check Steam first, many of them don't use Steam at all and don't mind paying higher prices to help support the developers.
