It's painful, but that's how it's going to be. The devs have real-life jobs and families, too. Besides, they're receiving the monetary support they need (>$3000 per month), so there's little incentive to churn out updates faster than required. I can only hope that this doesn't go down the Pizza Hot route of milking the game and blueballing for half a decade with biyearly updates.
Fortunately, the upside to the long wait is that there will be at least 2–3 hours of content so that you won't run out of gameplay so quickly... and these new minigames will keep you busy until the next update in July or August 2026.
