Delve 2.5.1

Delve is an endless room-to-room action roguelike for the Nintendo DS, now open source.

Fight through isometric dungeon rooms, pick one of three boons after every fight, choose your next door by the reward it shows, and go as deep as you can. When you fall, the gold you found buys permanent upgrades at the camp, and the descent starts again.

What's in the game

• Endless, seeded rooms: pits and chasms, traps, breakable props, explosive barrels, and doors that show what lies beyond them.
• Four areas, four bosses: the Dungeon, the Sunken Sewers, the Crystal Caverns and the Molten Depths, ten depths each. Then the order starts again, harder.
• A full kit: sword, dash, thrown daggers, and a blast that charges as you land hits.
• 13 boons per run, 15 permanent upgrades, and waypoints to start later runs deeper.
• Built for the handheld: three save slots, run history, first-time tips, a left-handed layout, touch menus, and closing the lid pauses the game.
• A secret behind the About screen.

1. Download delve-v2.5.1.nds below.
2. Copy it to your SD card and start it from your flashcart, from TWiLight Menu++ on a DSi or 3DS, or in an emulator such as melonDS.

Saves use DLDI; nearly every loader patches its driver in automatically. They go next to the ROM (delve-1.sav to delve-3.sav), or to /saves/. Tested in melonDS and on a Nintendo 3DS with TWiLight Menu++.
