Gameplay Balance — Tank 99 Steam update #1355704

Death penalty softened — Losing a life now drops your tank power by one level (minimum LV1), instead of resetting all the way to LV1. Late enemy mix eased — Higher-tier enemy caps are lower, and low-tier enemies are no longer stripped out after stage 50. Enemy AI capped — Late-stage AI difficulty no longer scales to full strength; endgame behavior sits closer to mid–late intensity. Smarter power-ups — Drop odds now scale with stage progress, your current power level, and the battlefield (enemy pressure, lives, active shield/timer/shovel, etc.). Underpowered runs get more Stars; saturated runs get fewer useless upgrades.
