Android games without DRM

### Android games without DRM:
================ Google Play ================
*** DRM needs to be verified game by game ***
- Death Come True, v1.5 (https://play.google.com/store/apps/details?id=jp.co.izanagigames.deathcometrue): tested until the mandatory/tutorial wrong answer, and worked fine; used a vanilla Android 13 without MicroG and on airplane mode.
- Sea of Stars, v1.1.59964 (https://play.google.com/store/apps/details?id=com.playdigious.seaofstars): tested until the first animated/animatic scene, no issues observed; used a vanilla Android 13 without MicroG and on airplane mode.

### Cases easier to identify:
=== F-Droid / Github / IzzyOnDroid ====
FOSS repositories, so usually DRM-free, and even if not, licenses should usually allow forking as DRM-free.

======== Humble Bundle / Steam ========
Yet to find any not DRM-free.

=============== Itch.io ===============
Usually DRM-free unless noted otherwise, from my experience.

============ [NSFW] DLsite ============
Games have DRM if they have a green information box under the "File format" / "Genre" / "Size" fields; otherwise are DRM-free.

============ [NSFW] Nutaku ============
All Android games are gachas.
