This games not for me. **Developer response:** Thanks for the feedback. I’ve already reduced the difficulty of the first area in recent updates, and I’ll keep improving the early-game experience to make the start smoother. Tip: Healing items can help you stay in top condition before tough battles. ### 5/5 — I like the game. *2026-06-19* Good art, story, gameplay and art design. The music is so cute. This is good, please everyone, give it a try. The game is not free of course, is a premium game. Still is worth and very cheap. **Developer response:** Thank you so much for the 5-star review and the kind words! I’m really happy to hear that you enjoyed the art, story, gameplay, design, and music. It means a lot, especially as a solo indie developer. I’ll keep working hard to improve the game and add more content! ### 2/5 — Can’t really play game *2026-06-17* There are so many ads that I can’t really play the game. It was very hard to even find the way to pay to remove the forced ads, but then there are still a bunch of things you can only get by watching ads even after paying to remove forced ads. The one plus is that the forced ad removal is pretty reasonably priced, but I was already sick of the game by the time I found it. This could be a fun game but the horrible monetization makes it no fun to play **Developer response:** Thank you for the feedback. Right now, interstitial ads are shown between some battles, and Premium can be unlocked from the Settings screen to remove forced ads. But I understand that the free experience should still feel comfortable to play. I’ll review the ad frequency and try to make it feel smoother and less disruptive in a future update. Thanks again for taking the time to let me know. ### 2/5 — Ad after every battle *2026-06-16* Uninstalled **Developer response:** Thank you for the feedback, and sorry about the ad frequency after battles. I’ll review this and adjust the frequency to make the experience feel smoother in a future update. Thanks for trying the game and for letting me know. ### 5/5 — Fun little old school-esque dungeon crawler. *2026-06-14* A fun little old school-esque dungeon crawler with a futuristic cyberpunk coat of paint and some rougelite elements. It’s like the old text based dungeon crawlers but from the far far future, if that makes sense. It’s great for quick bursts of action when you have a few moments of down time. I look forward to continuing my journey and unlocking more of the lore via the cute little built in terminal! Keep adding monsters and levels! Full disclosure, I received the ad free in app purchase for free. That being said, if your into this type of game, it’s worth spending money for the unlock. **Developer response:** Thank you so much for the thoughtful feedback! I'll definitely keep adding more monsters, levels, and secrets in future updates. Thanks again for playing and for supporting the game! ### 5/5 — Hackrun plus chips challenge *2026-05-19* Fun little game. Like the selection of background music. **Developer response:** Thank you for the 5-star review of the game. I hope you have a fun and enjoyable time playing it! ## Frequently asked questions about RPG Offline ### What is the gameplay like in RPG Offline: OS Core Quest?
