Verdict
The clearest difference is in-app purchases: LiquidMath at none against Astro Invaders's 6. LiquidMath also leads on ads (none vs shown) and ratings volume (7 vs 1). Astro Invaders's advantage is update cadence (weekly vs every 3 months) and iOS requirement (13.0 vs 17.0). On price, rating and device support there is nothing between them.
