Verdict

The call

The clearest difference is rating: Worm.io at 4.6 against Colossatron's 3.5. Worm.io also leads on monetization model (free with in-app purchases vs subscription) and update cadence (every 3 weeks vs every 2 months). Colossatron's advantage is ads (none vs shown) and ratings volume (1.3K vs 83). On price, in-app purchases and device support there is nothing between them.
