A tester caught a teleport problem my thumbs had missed
In a mobile game about commanding the dead, a misplaced button can matter more than another monster.
I'm Ingyoon An, the solo developer at Ancoach Studio in Korea. My background is dentistry; I began learning to code through online searches in 2022. Here is one small control change in Necromancer: Undead Legion RPG that I would have missed without returning testers.
Two thumbs, three layouts
Movement sits on the left, while attack, teleport and skills sit on the right. But a comfortable position depends on hand size and grip. After testers asked to rearrange the controls, I added three presets: Default, Right-hand cluster and Left-handed. Auto-attack also has a lantern button that can be toggled during a fight, instead of requiring a trip into settings.
Then a long-time tester pointed out a problem: the right-hand layout actually put teleport under the left movement thumb. Lifting that thumb to press teleport dropped the direction input. A blink meant to help you reposition could send you the wrong way.
I swapped the attack and teleport positions. It was a small change on the screen, but it addressed a real interruption in the movement-to-teleport action. I cannot finish testing controls with only my own hands.
Why that matters to this army
The central choice is what to do with eligible fallen enemies: raise them to reinforce your undead army, or spend corpses on an explosion. You directly move, attack and teleport alongside the legion; automatic attack and hunting are optional. Corpse explosion uses fallen enemies' corpses, not living allies.
Actual V18 gameplay, with HUD hidden and presentation camera, lighting and combat staging adjusted. This illustrates the battle, not the control presets described above.
Players of my previous game returned years later to help test this one, and one tester alone sent more than 1,000 pieces of feedback. A lot of this game has been built with them.
