What is Resizer?
Resizer is an inventive 2D platforming puzzle game made by Robert Alvarez that challenges players to solve compact single-screen stages by altering their physical scale. The core loop involves stepping through magical size portals to navigate narrow passages, move heavy crates, collect hidden keys, and reach each exit safely. What sets the experience apart is how shifting size directly affects your interaction with the environment, turning spatial constraints into deliberate physics puzzles. You can play Resizer directly in your web browser with no downloads or installation required.
Key features
- Size-shifting portals: Pass through specialized environmental portals to cycle between multiple scale variations needed for distinct obstacles.
- Object interaction: Push heavy boxes across the floor while enlarged to open paths or create jumping platforms.
- Springboard navigation: Bounce on mechanical springs to gain vertical elevation and reach out-of-reach ledges.
- Key collection: Locate and collect keys across each stage to unlock the exit doorway.
- Instant puzzle reset: Restart the current screen immediately whenever a misplaced block prevents further progress.
How to play
- Examine the puzzle layout to identify where the exit door, keys, and size portals are positioned.
- Use the arrow keys or the W, A, and D keys to guide your character across the platforms.
- Shrink your character down to navigate underneath tight ceiling gaps and gather tucked-away keys.
- Step into an enlargement portal to gain sufficient weight to push heavy boxes across flat surfaces.
- Bounce on upward springs to vault onto high structures that cannot be reached with standard jumps.
- Walk through the unlocked exit door to complete the chamber and advance to the next challenge.
Controls
| Action | Keyboard |
|---|---|
| Move left, right, or jump | W, A, D or Arrow keys |

Size transformation mechanics
The central mechanic in Resizer demands understanding how physical volume dictates puzzle solutions. When reduced in scale, your character easily fits through cramped spaces and ducks below low-hanging ceilings to recover keys. However, tiny form lacks the physical power required to shift wooden crates. Passing through an expansion portal enlarges your body, giving you enough mass to shove heavy boxes into place to form makeshift steps or trigger floor pathways. Because certain doors require keys while others require relocated boxes, choosing the correct sequence of size changes is essential to clearing every room without stranding yourself.
Tips and strategy
- Evaluate the room first: Scan the position of all size portals and exit doors before pushing any box, because moving an object into a corner can permanently block access.
- Use small scale for scouting: Shrink down early to slip through tight corridors and collect tucked-away keys before expanding to manipulate the terrain.
- Utilize springs effectively: Bounce on springs from a steady position to gain enough vertical boost to reach higher stone platforms.
- Turn boxes into stairs: Enlarge your character to push heavy crates against tall cliffs, transforming the blocks into stepping stones for smaller forms.
- Restart without hesitation: Press the R key to reset the level immediately if a crate gets stuck against an immovable wall.
