Evaluation
Project R4T is a free, short single-player puzzle game released on December 16, 2022 as a student project by solo developer Myre36. The developer explicitly stated in a September 28, 2023 post that the game is "very simple" and that they are "unlikely to work on it much further after release unless there are some game-breaking bugs." That same post also discussed a potential sequel (Project R4T5) but confirmed it was off the table indefinitely due to scheduling constraints. No DLC has been announced or listed, and the store description presents the game as a self-contained short experience. Since launch, the developer has moved on to releasing two separate games — Project N3T (October 5, 2023) and Project Gravity (February 12, 2025) — and announced a third, Ødeborg, due August 4, 2025. All of this activity confirms the developer's attention has shifted entirely away from Project R4T. The game launched as a complete, finished product and has received no post-launch content updates.
Evidence
Developer explicitly states they are 'unlikely to work on it much further after release unless there are some game-breaking bugs,' confirming Project R4T is essentially complete.
Developer confirms the planned sequel Project R4T5 has been indefinitely shelved, with no future content path for the Project R4T series in the near term.

About this game
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.
