Terrible Lizards on Steam Deck

Terrible Lizards is Playable on Steam Deck. That is Valve's word, and it is a lower badge than Verified. Playable here means the default control layout works, the on-screen prompts use Deck button icons, and the default settings are described as performing well. It also means two limits: on-screen text may be hard to read, and you cannot hand the primary player role to an external controller.

Proton, because there is no native Linux build

The Steam page is a Windows game. There is no macOS depot and no Linux depot in that listing. Deck runs the Windows build under Proton. I am not recommending a specific Proton GE build. The compatibility report is about the default Steam setup, and that is the setup I will stand behind.

The PC bar the report sits next to

A review mentioned hitching on a desktop the writer called a Steam Machine. That sentence is about a desktop, not a Deck handheld session, so it does not become a Deck frame-time claim on this page. The system-requirements page keeps the same two tiers for people choosing a PC.

If you need larger text, the Deck itself can scale the interface, and the demo's hint-paint guidance toggle is a separate feature described on the beginner page. I do not have a confirmed in-game UI scale percentage, so that cell stays empty.
