Trenchglow

TRENCHGLOW started as a Mini Jam 209: Deep project. It was just a tutorial level, a slice, with underwater movement, sonar vision, and pressure-plate puzzles. Development is now paused, but this build now adds Chapter 1 (four levels), as I promised at jam prototype release, that I'd make a few more levels. 

Bug reports are welcome in the comments; share your time, gem score, and grade if you like chasing leaderboards. I hope you enjoy, and thanks for playing!

CONTROLS 

• Swim: WASD or arrow keys (swimming up uses stamina!) 
• Sonar Pulse: E, or LMB (Left Mouse Button) 
• Boost/Dash: SHIFT keys 
• Skip Song: TAB key

SUMMARY

2D deep-sea trench run: sonar in the dark, thread fast mines, grab gems, reach the exit. One timer for all four levels. Death restarts the level; gems respawn — the run is about routing, precision, and score, not a no-death clear. Puzzles are simple; the skill is maneuvering and chasing a better letter grade.

GAMEPLAY

• Four levels, one chapter clock. Gems: Ruby 1 · Sapphire 5 · Diamond 10 · Prismatic 30. Grade = gem score + time bonus (up to +100 by ~8:00); you need both a solid gem haul and strong combined score. 3+ deaths caps rank at B.
• Swim / rise / dash — stamina limits boost and climb.
• Sonar reveals the trench briefly; commit your line.
• Mines kill in one hit; many are large and fast.open mostly linear paths — light puzzles, heavy execution.
• Clear Level 4 for results: time, gem score, breakdown, deaths, letter + rank title.
