*2026-04-18*

I’m not too far in yet, but so far I’m loving the battle system. As someone who raises beetles, it’s clear that the developers put a lot of thought into the mechanics of raising larvae.

### 5/5 — 幼虫の育て方

*2026-03-18*

幼虫ってどうやって育てたらいいかもわからないしカブトムシしかいないのも不満
もっとヘラクレスとかクワガタとかを追加すると面白くなると思う
まじで幼虫の育て方を教えてください

### 5/5 — New favorite

*2026-03-13*

Amazing game, just stafrted and i'm already having fun. A classy mobile game with a unique concept. Just one question, will my beetle lay larvae on its own, or do i need to do something to allow it to?

**Developer response:** Thank you for playing and for the kind review! I’m really happy you’re enjoying the game.
You don’t need to do anything special — they will naturally leave offspring as time passes.

### 5/5 — Very fun
