Daily challenges, global leaderboard, login streak rewards. Cosmetic shop unlocked entirely through gameplay coins — no ads, no in-app purchases. Available on App Store and Google Play.
Hey Product Hunt! I'm the developer behind Swipe Slip.
I started this as a personal project to explore what Kotlin Multiplatform could do for a real, production-quality mobile game. What began as a tech experiment turned into 500 hand-crafted levels, 8 difficulty tiers, a daily challenge system, and a global leaderboard — all from a single Kotlin codebase.
The biggest decision I made early on: no ads, no IAP. Ever. The game is completely free. You earn coins by playing well, and spend them on cosmetics. That's it. I wanted to build something I'd actually want to play, without the monetization dark patterns I find exhausting in most mobile games.
I'd love to hear your feedback — especially if you make it past Expert difficulty. Most people don't!
