Verdict

The call

The clearest difference is in-app purchases: Deep Moon at none against Block Invaders's 2. Deep Moon also leads on update cadence (every 2 months vs every 12 months) and iOS requirement (11.0 vs 16.0). Block Invaders's advantage is ads (none vs shown). On price and device support there is nothing between them.
