I like it a lot! Mechanics are really fun, even if things get repetitive after a while. I like the idea of having multiple playable characters - for instance by saving a new slave from the slaver, or by beating a boss. Like an alternative choice for an archer or the sword.
I'm not entirely sure how the world map works. (Does it have like 1-1, 1-2 and more? I've only manged to get 1 win streak and I'm not sure how many you need to get to the tower, if that's implemented yet.)
More locations would be nice, maybe some passive boons?
How do enemy spawns work? If they're entirely based on chance, an unlucky player could get overrun very quickly and a lucky one would get barely any? Or does the game have a set amount of monsters to spawn for each 50 steps?
I did found a bug. For example you could use the archer's ability to shoot 3 arrows at 3 lanes. The first two could hit an enemy, and you could cancel the attack before the third lands. Doing this allows the archer to move again, though the energy is used, and the two enemies got hit.
Overall this game is really good! Even mobile there's no freezes or anything. Looking forward to new content, don't push yourself too hard dev or devs.
