Read full description

Leveling Boost is a fast-paced, tap-and-play RPG built around one core idea: every battle makes you stronger — if you choose wisely. You play as Shesh, a humble farmer thrown into a world overrun by monsters. Each enemy has its own health pool, and after every victory, you absorb a percentage of their HP to grow stronger. But one bad decision can cost everything. Tactical Combat • Your HP is always visible on screen. • Enemy HP appears the moment you step onto their tile. • Compare, decide, then engage only when the odds are in your favor. Smart Progression • Every win permanently boosts your health. • Lose a fight? Come back stronger and claim revenge. • Progress is earned through strategy, not grinding. Compact Living World • Explore multiple regions filled with unique enemies. • Cleanse each zone step by step as danger escalates. • Designed for short sessions and instant readability. Final Challenge • Defeat increasingly powerful foes. • Unlock new areas with every victory. • Face Rasha, the world-devouring tyrant, in an ultimate showdown. Seamless Play • Automatic saving — continue anytime. • Optional reset to relive the challenge from the start. • Dynamic music and sound effects that react to combat. Can a fragile farmer become the world’s last hope? Plan carefully, grow stronger, and bring down Rasha before it’s too late.
