Ask HN: What are you working on? (September 2026)

I should clarify that I'm currently spending a lot of time building the engine (tank movement, physics, etc.). After that, I'll introduce more of the storyline, maps, and levels.

The game has 3 modes. "Protect the frog", where you must protect the frog. "Hunt", where you hunt for opponents' frogs and "Destroy", where there is just annihilation.

U can change the mode by switching to "build" and then going to "map". There you can set everything. From tanks to mission to waves, etc etc... The idea is that the switching between build and play is as seamless as possible.

So the tradeoff this database makes is it doesn't work at high scale, but it has a lot of features not typically in a database, such as:

- The ability to embed non-turing-complete event source handlers in the database schema

- Categorical type system that makes migrations provably secure

- All schema changes take place through migrations

Example syntax:

  Inventory = aggregate(key = sku) {
      sku:       String
      name:      String
      available: crdt(merge = counter) I64

      command Stock(sku: String, name: String, qty: U64) {
          sku       = input.sku
          name      = input.name
          available += input.qty
      }

      command Reserve(sku: String, qty: U64) {
          available -= input.qty
      }

      command Release(sku: String, qty: U64) {
          available += input.qty
      }
  }

  command SubmitOrder(order_id: String, party_id: String, sku: String, qty: U64, total: U64) {
      Order::PlaceOrder(
          id       = input.order_id
          party_id = input.party_id
          sku      = input.sku
          qty      = input.qty
          total    = input.total
      ) compensate Order::Cancel()
      # `sku` is Inventory's key — the step must bind it so the engine can
      # resolve which Inventory row the command targets (task-212).
      Inventory::Reserve(sku = input.sku, qty = input.qty)
          compensate Inventory::Release(sku = input.sku, qty = input.qty)
  }
