About Project R4T

✦ AI summary

Project R4T has you control a test subject navigating a facility by manipulating your own size and weight to solve physics-based puzzles, platforming challenges, and unlock paths forward. The game's clever twist is that shrinking makes you lighter and faster while enlarging weighs you down, forcing you to strategically balance your dimensions against pressure plates, closing doors, and tight spaces while an observant AI overseer comments on your progress.

Take control of a test subject tasked with testing out a new device capable of shrinking and enlarging the user. You will be tasked with completing tests, all designed around the tester's height and weight. Platform, collect keycards, and fit through small gaps in this short single-player experience.

Features:

You can make yourself larger and smaller with a simple press of a button. With this, you will be able to fit through small openings. However, your size affects your weight, so you must keep that in mind as you might encounter a pressure plate that will take your weight into account. Additionally, your weight determines your speed, letting you jump over large gaps or run through doors before they close.

As you solve puzzles, the Overseer will observe your performance and talk to you as you play. You will get to know him, and the difficulties he faces at the facility.

✦ AI summary

Project R4T is a short game that players praise for its fun movement mechanics, witty narrator, and accessible design that runs well on modest hardware, though they consistently note its brevity and desire for more content. Common complaints include overly sensitive camera controls, occasional glitchy collision detection with walls, and basic level design that could use more creative puzzle implementation. Players seem to view it as a worthwhile free experience, though those wanting substantial content may find it too brief.

Pretty good game but still they could add some more stages/levels and/or the settings because the camera seensivity is TOOOOOOOOOO HIGH but still great game
Recommended Apr 19, 2026
Project R4T is a very short experience that can be finished in about 10 to 15 minutes. It does not try to be more than it is, which works in its favor. The narrator is sarcastic and sometimes rude, which gives the game a bit of personality. This style will not appeal to everyone, but it does make the experience more memorable. It is still clearly an amateur project, but it is focused and does not overstay its welcome. I would rate it 4 out of 10, and it might be worth trying if you enjoy short and simple free games.

The walls and floors are super glitchy as you run but not the objects weirdly enough

I like this game! Sure it was short, but the physics was decent, and I was not disappointed, would love to play more of this if you ever decided to make a longer game!

very short game with some easy puzzles but great movement. i love being a speedy lil mouse and jumping everywhere its so fun omg i love jumping and bouncing off walls and being fast. level design is a lil basic and makes the environment feel barren and i feel like it and the puzzles could have been used a bit more creatively (like maybe something with a vent or a giraffe fight) and i feel like some visual and sound effects for the size changing would add a lot. but the dialogue is quite funny. I will say im not sure if all of this is OSHA approved but i fear you dont give a r4ts ass about that. i love the movement tho so i approve.

honest to god even though this started as a student project i actually love this game the concept of it is amazing and the voice acting? so peak i also love the simplistic setting and puzzles because it is so easy for my laptop to run and that makes me very happy all in all i love this game and i really hope the creators make R4T5 !!!!

Games like Dying Light are easy to find if you only want parkour or only want zombies. These eight keep the part that matters: a city that becomes a different place after dark.

Games like Portal 2 all share one habit: teach a single impossible trick, then spend a campaign breaking it. From rewinding objects through time to Escher geometry that loops back on itself.

Planet Coaster DLC: skip the collection, buy the packs

The Planet Coaster DLC catalogue closed in 2019, so there is no curve left to wait out. Our record shows the collection bundle costs far more than assembling the same packs one by one.
