RocketMan A VR Videogame Created With Unity Save

The Virtual Reality escape-room videogame RocketMan, realized for Oculus Quest (1 and 2), takes you into an apocalyptic world. The goal is to escape the Earth thanks to a rocket that you will first need to repair and set up through various riddles. You can move by walking, teleporting, or by using the joystick of the controllers. To solve the riddles, you have to use various tools that you can pick up using your hands or through magnetic grabbing.

The game was realized in the frame of the course CS-444 Virtual Reality and it was awarded as the best game of the course for year 2021/2022.

How to play

The game was built as an .apk file of 139 MB. Download the game from here (if the download link expires, please contact me). To install on your Oculus Quest an apk that does not come from the oculus quest store, you can follow one of the many tutorials on the web, like this one.

Gameplay Trailer

The GIF and video that follow contain some gameplay scenes that might represent a spoiler of the solution of some riddles in the game. Be aware of this before watching them, if you want to play the game. Since GitHub doesn't let upload videos bigger than 10MB, the video had to be compressed and the quality is much lower than the original. :(

How to open up the project on Unity Editor

This game was developed using Unity Editor 2020.3.32f1, we suggest you to download this version because different ones (especially older) might give problems.

Once you've downloaded the repository ( warning: it's 1.17GB) and extracted it into a folder, open up the folder CS-440 using the Unity Hub. If the version of the Unity Editor you're using to open the project is the correct one, no error should appear.

Quick presentation slides

The following presentation is a summary of the main features. For a detailed explanations of the realisation of all aspects of the game, please read the file report.pdf.

Aesthetics and immersion design

The game was thought to be played on a portable device such as the Oculus Quest, so we decided to use only low poly assets that could easily be rendered without a drop in the frames per second. That helped us also to find much more assets from the web with a compatible graphic style, creating an environment which is thematic consistent. In fact, the game uses nineteen different external assets’ packages, but the whole scenes were made by placing manually every single prefab, recreating a rocket environment as we imagined it since the very beginning, without using any pre-made scene.

To improve immersion, not only we tried to make interactions as natural as possible, but we also provided each of them with a proper sound effect and some haptic feedback. The music in the background was chosen to be relaxing while the player is reasoning on riddles. A big part of our attention was put in the rocket and capsule launch animations, so that they could convey as much as possible the emotions and feelings of a real launch. For them, every sound and particle effect was carefully designed.

Play testing and feedbacks

The feedback we got from the play test was very valuable, as it allowed us to see what parts of the game were not very intuitive. For example, we noticed that the flashlight on the second floor was too hard to find, and people would forget they could interact with items with a button, so we decided to have the flashlight on by default instead of toggling it with a button.

Moreover, many testers said that the tutorial was long and not intuitive due to the amount of text. Hence, we replaced most of the text with videos showing the interactions. Some people also forgot some parts of it, so we introduced an animation at the end of it that moves the tablet showing the videos on the wall, where it will always be available. We also had other minor comments, such as missing sounds indicating success or failure in some riddles, so players didn’t know if they had successfully completed the riddle or not.

Every comment or minor bug encountered has been noted down and solved. Other than that, every participant said it was a funny and immersive experience, without any kind of motion-sickness except for a player that felt slightly destabilized by the climbing.

🛠 Skills

C#, Unity Engine, Oculus Framework, Blender, Photoshop, Adobe Premiere Pro. Game design, development of the game mechanics from scratch using only the Unity engine and the basic Oculus Framework for Virtual Reality interactions (the popular VRTK was not allowed, as it had most of the common vr-mechanics already coded), realisation of the whole game scenes from scratch, using Unity Store's assets but only of single objects, not whole scenes. Premiere Pro for the realisation of the gameplay trailer. Tons of debugging experience made through this project :). Playtesting. Manual realisation of small assets with Blender. Photoshop for the realisation of some game materials and for the game's logo.
