Vavada

Vavada's space shooter features a coin economy that supports persistent ship upgrades: coins collected from defeated enemies and completed stages can be spent in the shop to improve your ship's capabilities between sessions Upgrades increase base stats, firepower, health, movement, that affect every session following the purchase, meaning a returning player is measurably more capable than on their first run. Power-ups dropped in-game provide temporary bonuses on top of the base ship stats, so an upgraded ship using a laser beam is more effective than an unupgraded one using the same power-up. Boss fights at every fifth level provide the clearest demonstration of ship upgrade impact, as their multi-health-bar structure requires sustained damage output that upgraded weapons deliver more efficiently. Vavada's shooter, puzzle, and runner are all available offline with no internet and no registration.
