KryptVault

Every upgrade helps you and hurts you at the same time. Pick carefully.

KRYPTVAULT is a small arcade roguelike where the dungeon never stops. Waves flow into each other, the walls reshuffle around you, and every level-up deals you three cards. Each one is a trade: more damage but a slower trigger, more speed but thinner skin. If you're feeling brave, there are cursed cards that make you stronger while making the whole crypt meaner.

There are 21 upgrades and 4 evolutions, with no free lunches anywhere. Combine Shotgun and Homing to get the Seeker Swarm, or Pierce and Damage for the Railgun. You can play three classes: a tanky Warrior, a fast Rogue, or a glass-cannon Mage. Bosses rotate between the Charger, the Summoner, and the Spiral. There's a global leaderboard with arcade-style initials, a portable TAG#0000 identity, and a vault key that logs you in from any machine. A daily challenge gives everyone the same dungeon once a day, and the Vault lets you bank coins between runs for permanent upgrades.

The whole thing is one HTML file. 

Controls: WASD or arrows to move. Aiming is automatic, so your only job is positioning and card choices. P pauses. On mobile, drag to move and tap to pick a card.

One warning: stay off the screen edges. The crypt doesn't like campers.

This is a playtest build and I want brutal feedback in the comments. My current record is wave 8. Beat it.
