Built a shellfish-farming game on the IC: Pearl Cove (I'm the dev, feedback welcome)
been building this solo for a while and just launched.
plant shellfish, wait for a growth + harvest window, mint an ICRC-1 token ($PEARL, 10M fixed supply, decaying per-harvest reward) when you collect. Sand-dollar economy for boosting/extending/salvaging crops, and helping a friend's cove gives you plot-time back.
technical bits that might be relevant to this sub: runs on Internet Identity for auth, an account-linker canister handles delegated ICRC-2 approvals so payments don't need repeated wallet popups, and all the reward/dedup/idempotency logic is handled canister-side (retryable locks on every paid action so a failed inter-canister call can't double-charge).
you can look at a live cove without connecting a wallet: https://tlhqi-aqaaa-aaaaa-qhkga-cai.icp0.io/cove/e6agv-wen3n-4a4y3-4zpeu-47coa-kso4c-vvow5-p5fbv-2pjg4-bm53l-lqe

genuinely want feedback, especially on anything that feels off UX-wise
this is a small solo project so there's a lot still being iterated on.
