Wallwave is a maze-building roguelite tower defense. Enemies have no fixed road: you carve their path wall by wall, and every wall you place fights back. Draft relics between waves, unlock new towers as your total cleared waves grow across runs, and survive 20 waves — then push into Endless mode for as long as you can hold the line. - Build the maze: force the longest, deadliest path you can carve - 7 tower types across 3 upgrade levels - 12 relics to draft between waves - Roguelite meta-progression: towers unlock as your total waves grow - 10-15 minute runs, offline-friendly, no login required - No ads inside the game

Verdict
The clearest difference is ads: Wallwave at none against Melt and Fill's shown. Wallwave also leads on update cadence (every 5 days vs monthly). Melt and Fill's advantage is iOS requirement (13.0 vs 15.0). On price, in-app purchases and device support there is nothing between them.
