If you think Steam or PSN-markets are comparable to Amiga, that's on you. You may or may not support development of Amiga game. You decide.
I was polite. No rom is worth $50 for any platform. I would rather get it included with and get an entire machine with the A1200 max than pay $50 for one rom. Seriously. 95% of your customers here do not own Amigas, they just want to emulate the game.
Let me rephrase. "This is the most expensive modern retro platform rom I have ever seen, EVER, in the last 20 years. Also the most expensive rom I have ever seen on Itch".
Now I am sure you will say how Amiga is special and all the other platforms with 10 to $20 roms (max) are somehow easier to code for and that's the reason.
I watched some gameplay and the SFX are way, WAY too loud anyway. Shockingly so, as to turn up the volume to enjoy the (very good) music, you'd have to blow your ears apart with the overbearing SFX. I have not seen any videos where this is adjustable, but I do hope it is.
I let others do the talking. I heard some people claim this is the best shmup on Amiga, or one of the best releases in the past 30 years. That's no me, that's actually games players, and you can google up some of those comments. Anyone who ever actually played the game says it's totally worth the price. If you'd prefer to comment or cry about the price rather than have fun with the game, then be it.
