I really really love this game, as someone that always loved the style and atmosphere of the original game, but was too bad at it, to enjoy it consistently. Which is why i'm really happy the mobile version is much easier to get into casualy. Now, seeing as the game is free to play, i'd still like to give something back to the devs here. Yes, there is theonite, but after roughly playing for a week, i haven't felt the need to spent much of the currency i have got by playing - though maybe that changes when i get farther into the game. That's why, for me buying more theonite doesn't interest me too much, which is why i'd suggest giving us the option to watch ads in return for a small amount of theonite. Giving it a cooldown or a max amount of ads you can watch per day would probably necessary however. I'll probably buy something soon anyway, just to throw some support at the devs, but i think this suggestion would let f2p-players also support the game, even if only a little bit. Another suggestion to make buying theonite more attractive could be adding special items to the shop, like the extra announcer voices of the original game for example. As someone that hasn't played enough of the original game, i don't know how much unused content there is left from the original, aside from the characters. But if there's more things like the announcer packs that could be sold, like unlocking voice lines or unique animations for characters - i think that could be fun as well. tl;dr: Let us watch ads for a small amount of theonite on a cooldown or max-per-day basis, so f2p-players can support the game. Also putting more unique items in the shop, like announcer voice packs, or unused Animations and voicelines for characters - so you can spend money on something else than Relics.
