INVERSA

What is INVERSA?

INVERSA is a precision platformer built around one core mechanic: flipping gravity. At any moment, you can invert your gravitational pull and run across ceilings, dodge spikes from below, and stomp enemies from unexpected angles. Master the flip and the world opens up. Mistime it and the void reclaims you.

How to Play

| ← → / A D | Move |
| SPACE / ↑ / W | Jump | 
| Z / X | Flip gravity|
| C / SHIFT | Dash |
| P / ESC | Pause |

Collect every gem on the level to unlock the portal, then reach it to advance.

Features

- 5 handcrafted levels: each with its own layout, hazards, and enemy density, growing from tutorial-gentle to brutal finale

- Gravity flip mechanic: invert gravity on a short cooldown; the ceiling is your second floor

- Air dash: blast through enemies or close gaps; dash-kills score bonus points

- 3 platform types: normal, ice (slippery), and crumbling platforms that disintegrate under your feet

- Checkpoints: mid-level save flags so a single death doesn't cost you everything

- Enemy variety: patrolling walkers and hovering diamond eyes; stomp or dash through them for combo points

- Combo system: chain gem pickups and stomps to multiply your score

- Speedrun timer: each level tracks your clear time with time-bonus scoring; best times are saved locally

- Level select: replay any unlocked level to chase better times or higher scores

- Procedural ambient soundtrack: a generative drone that evolves as you play

- Parallax star field: the void always looks good

Tips

- Flip on the way up through a gap, you arrive on the ceiling already running

- Crumble platforms give access to secret areas and bonus gems, but don't dawdle

- Dash through enemies mid-air for +150 instead of the +100 stomp bonus

- Ice platforms carry momentum; use them to build speed for hard jumps

- Find the hidden secret on each level for a +500 point bonus
