So... as someone who has played a lot of mobile games (or mobages) and gacha games, this entry hurt me. Congratulations!
That said, I'm afraid I didn't enjoy this entry. The lack of decent movement soured my ability to strategize and without the ability to counter attack, every map kind of boiled down to 'let someone tank and go to town.' Which wasn't easy due to such a wide variety of reasons.
First... the gacha mechanic. I understand why it's popular, but I didn't particularly enjoy being subject to random chance and getting three Rodneys in a row. Hits a little too close to home if you read my first line. As well, in order for a gacha mechanic to be successful, it needs to have some sort of higher return value or at least the suggestion of something the player wants. Having it be completely opaque meant I never felt like rolling the gacha was really any worth it once I got my team of Rodneys. Sure, I got a magic caster after that, but they didn't have the same range of movement as my cavaliers, who quickly became my most important units because, well... they could actually move.
That's my second misgiving. Two to three movement isn't bad. But you need to design your maps around this gimmick. Maps felt like a slog just waiting for units to approach each other with obstacles that all may as well have been walls for how well one could move through them. Any map with obstacles just felt very 'chokepoint-ey' and not very engaging. It didn't feel like I had an army, more like I had a stationary turret. There was no real option to disengage and rearrange my army. Once I committed, that was it. The lack of free movement meant it was too difficult to restructure my approach and made it very dependent on my initial formation. Which, to be fair, isn't always a bad thing, just not my style.
The third though. Another pitfall of the gacha mechanics. The grind. Oh my lord, the grind. You did level up very fast, that I will admit. Gold was frequently not a problem. So much so that I hesitated to think it mattered. Maybe making the drawing currency much more plentiful and giving the summoning mechanic the ability to give you weapons to distribute would have made the gacha more enticing, and thus allowed you to raise the price of simply purchasing the weapons to skip that facet of the gacha also enticing. Rather than just something you had to menu through because why even think about gold when you have to struggle through leveling up so much to get anything done?
But still, the grind was unfun. I do not like grinding the same thing over and over and over again. At all. I did that enough in my time spent playing awful mobages. You ever played Phantom of the Kill? I was really reminded of that, but this just had more mechanics that I couldn't reconcile with. Between the awful, awful hub town UX, the constant grinding, and the unsatisfactory numbers in every respect, I just couldn't stick through with this game to even half way. I will, at least, note that the idea has merit if executed a lot better, though. The dialogue was also pretty on point as well, if kind of sparse.
