Angel Engine surgery uses a mechanical arm for treatment minigames while equipment upkeep and time pressure compete for your attention. The official Steam description establishes that loop, and the achievement list names syringe, laser, maze and sewing tasks. Sources reviewed on 2026-09-20 support those task names and conditions; exact current-build techniques and a complete input map remain To be confirmed.
Shared control principles
Read the current prompt and manual for the active task. The official store's feature list describes minigames at a high level, without tool bindings or an ordered control sequence.
As a demo/community observation, a demo player reported LMB interaction, RMB closing or turning, and manuals for operation details. These reported room inputs do not establish the controls for every surgery task.
An independent full playthrough by Alpha Beta Gamer is an observation source, not an official control reference. No exact technique from it is claimed as reproduced here; a visible outcome cannot supply missed inputs or unlock conditions.
Syringe
The official achievement “First try” has the condition “Complete syringe minigame without making any changes.” Official Steam achievement list.
This confirms the syringe minigame and that specific condition. The description does not explain what counts as a change or give an input sequence. Current-build controls and a repeatable technique remain unverified.
Laser
The official achievement “That was hard” has the condition “Complete any stage of laser operation minigame with all arrows facing the same direction.” Official Steam achievement list.
The condition does not establish an arrow-key binding, a solution for a particular board, or the stage at which the laser becomes available. Those details require current-build verification.
Maze
The official achievement “Can’t Stop Me Now” has the condition “Complete maze operation minigame in 3 seconds.” Official Steam achievement list.
That is an achievement target, not a general time limit or a verified path through the maze. A route, control mapping, and timing strategy are unavailable in the reviewed official description.
Sewing
The official achievement “And the swiftness of the doctor…” has the condition “Complete sewing minigame with clicking incoming titles with less than 1 second delay.” Official Steam achievement list.
The word “titles” is retained from the retrieved official description. This source does not establish the corresponding controller input, the whole task sequence, or a reliable technique for meeting that condition.
Fuse, power, and overheat
These are the relevant official achievement conditions, not a universal safe-play threshold or recovery recipe. All rows are transcribed from the official Steam achievement list.
| Achievement | Official description |
|---|---|
| Another One Sparks the Fuse | Replace 100 fuses |
| Goodbye darkness my old friend | Restore power 10 times |
| This is fine | Have Angel Engine overheat on 95% or more and discharge it |
| Fear of the Crank | Complete operation without any power shortage (It must be done in level where Power Shortage is active) |
| Mr. Paranoid | Complete whole operation without Angel Engine overheat raising above 20% |
The thresholds belong to different achievement conditions. They do not prove a normal operating range, fuse spawn rule, discharge control, or exact power-restoration sequence. Follow current in-game equipment instructions rather than treating this table as a maintenance procedure.
Platform input differences
There is no verified mapping from the cited demo mouse inputs to released-build controller or console controls in this guide. The demo discussion cannot establish equivalence between platforms, and the Steam achievements document conditions rather than input bindings.
Record your build, platform, and input device when comparing a playthrough. The beginner guide covers the available preparation evidence; the achievement reference preserves all 30 official entries.
