Hero's Quest is an indie Roguelite RPG with automatic fights and lots of incremental progress.
Developers without huge budgets & teams need to do their best with what's available - like free assets packages. Here, both monsters & characters are nicely crafted, dynamic fantasy 2d arts. That means some cute slimes, angry animals, but also huge bosses full of spikes & tentacles. Unfortunately, they are not animated in any way - just slightly floating around. That's what you'll be seeing the most time - 2 characters standing next to each other and likable special effects appearing here and there. That's just like in super-old-school RPGs. The rest of the visuals are also heavily inspired by titles published decades ago. On the map/outside fight, characters, enemies & environments are created using pixel-art - somewhat repeatable but not tiled, so scenes look picturesque and lively. UI is also pixelated, bringing back memories of some antique titles - and there are excellent soundtracks in the background.
The gameplay is divided into runs - limited by energy, meaning 20 fights (might be extended by defeating bosses). Your job is to run around & approach an enemy with the right level - high enough to get some exp, but not too high to avoid loss. After the fight, you'll be able to distribute stat points - or you can automate it in a way that fits your playstyle. Then, after running out of energy, you can spend earned gold - or it'll be converted to "tickets" - rare currency. You can get equips & relics with gold, increasing stats by massive amounts. Tickets can be used for things like opening slots - and there's also a skill tree system, with currency gained from killing bosses. Also, with tickets (and real money), you can get new heroes & skins - meaning some passive bonuses - or just new visuals. Also, you can check leaderboards & achievements from the Play Games service.
The game will show ads in several places - reward ones when needed, short forced ones after a run, and even ad banners here and there. If that's a problem, you can purchase no-ads powerup, ad-skip tickets - or just get tickets as if they were premium currency.
