Combat in Ylem's Cat pairs Molly, who fights with a melee weapon and a bow, with Mio, who fights on its own initiative in whichever of its three body forms the player has chosen. The developers describe the core logic as cooperation between the two rather than solo combos, and combat is roughly one third of the game alongside exploration and puzzles.
Everything on this page comes from a press-only demo running about an hour, shown in August 2026, and from what the developers have said they intend to build. None of it is final, and the game has no release date.
Molly's Melee
Melee splits into a light attack and a heavy attack, which chain into combos and into derived attacks off the end of a chain. A charge attack and a dodge round out the ground move set. Aerial and jump attacks do not exist yet; the producer has said they are planned for later, and that at present the game is ground combat only.
Molly's Bow
The ranged weapon is a bow with two distinct shots. Holding to aim produces a charged shot that does more damage and that the player has to place; a short press fires a normal shot that homes in on its own. The split between short press and long press is a locked design decision rather than something under review. One skill adds a brief stopping effect on the completion of a charge.
Linked Attacks
The attacks the developers care most about are the coordinated ones. Finishing a base combo and then timing Mio's attack into the opening produces a stronger, wider strike than either character lands alone. Growth in Mio's half of the skill tree goes into these linked attacks rather than into new attack types for the cat.
Knowledge Applied to Fighting
Fights are built to reward the same kind of realisation that opens doors elsewhere in the game. Understanding an enemy is often worth more than out-damaging it. The examples the developers have given are these:
Situation | The knowledge that solves it |
|---|---|
A shielded Sentinel | The shield can be worked around two ways. Repositioning and switching Mio to a form that can flank behind breaks the guard. The shield also carries an eye that resembles the heads of other Sentinels; putting an arrow into that eye bypasses the shield entirely, and with the right bow skill it immediately triggers a ranged linked attack. |
An overheating enemy | Some mechanical enemies enter a glowing orange overheat state that reads like the wind-up to a heavy attack. A coordinated skill with Mio interrupts it. |
A flying enemy | The big cat's leap destroys the enemy's flight device and brings it down, after which Molly's ground melee can reach it. |
Progression
Defeated enemies drop two separate currencies: experience, which levels Molly's skills, and rapport points, which level Mio's. The demo's skill screen had seven branches:
Branch | Covers |
|---|---|
Shared human skills | Skills that apply across all of Molly's weapons. |
Light attack | The light melee chain. |
Heavy attack | The heavy melee chain. |
Ranged | The bow, including the charge stop effect. |
Shared cat skills | Skills that apply to Mio in any form. |
Medium cat | The utility and flanking form. |
Big cat | The mount and heavy attacker, including mounted combat. |
The producer has said the demo's experience rates were tuned upward specifically so that testers could spend points freely in an hour, and that the skills shown were far from all of them. Numeric growth exists but is deliberately kept small, so that raw stat increases do not overshadow the knowledge-driven core of the design.
Equipment
An equipment slot was present in the demo's menu but switched off. The producer has since said there will be a small equipment and accessory layer, describing it as a loadout of modifiers rather than a full gear system with tiers and drops. No individual piece has been named or shown.
Enemies and Bosses
Every enemy in the demo was humanoid and mechanical, and the demo closed on a boss-class one. The producer has confirmed that non-humanoid bosses will exist in the full game, and that the roster is not limited to machines. The reasons given for leaning on mechanical enemies are that they suit the light science-fiction setting and that a seven-person team cannot cheaply author large numbers of organic creatures. The Sentinels page covers what is known about them.
Known Issues in the Demo Build
Ranged combat substantially out-performed melee. It was possible to beat every enemy in the demo, including the boss, by keeping distance and using the homing shot. The producer has said one rebalancing pass is already done, and that the goal is skill trees and builds that make either choice viable rather than punishing one of them.
Slow-motion effects and combat close-ups are already implemented, but testers largely did not notice them; the producer attributes this to the demo packing too much into a small space.
Camera protection against scenery blocking the view, and better target locking in group fights, are both planned but were not in the demo.
