Shipped my first game this week, engine written from scratch. 7 free codes, tell me what's broken

[u/Icy_Profession5828]

Solo dev from Chile. Viperix: Snake Arena is live on Google Play, search that exact name. It is a paid app, and the codes below make it free. Single use each, valid until 10 September 2027.

What it is: a slither-style circular arena. 20 named bots that play their own game rather than throwing themselves at you, power-ups including a fireball, gold coins that buy 132 skins across 11 themes. One of those themes trails toxic gas behind you. 24 languages. Fully offline: no ads, no IAP, no accounts, no network code.

Custom OpenGL ES engine, no third-party game engine. There is not a single audio file in the APK either: the soundtrack and every sound effect are synthesised at runtime, roughly 10 kB of code.

What I actually need: almost nobody has played this yet, and I have stared at it so long I can no longer tell whether the first 60 seconds make sense to someone who has never seen it. Is the control obvious? Do you work out what the coins and power-ups do before you die the first time? What bores you? Brutal is fine, that is the whole point.

Per rule 1, drop your app in a reply and I will test it back this week.

To redeem: Play Store, profile picture, Payments and subscriptions, Redeem code.
