Very cool and atmospheric game, with simple visuals made very immersive by the simple but effective use of post processing. I loved the atmosphere, though using sounds would make the game even more immersive.
The "expansion" theme didn't really shine through in the game, since I basically couldn't do nothing with the "memories" I collected, but the game was fun nonetheless.
I run into a couple of issues while playing the game and have some suggestions for improvement:
- I wouldn't suggest using 7zip for compressing the game: It's not a common format for games and windows doesn't support it natively like .zip or .rar, so you can't be sure that everyone will be able to unzip it to play the game;
- I don't know if this was intentional, but you can climb tilted walls by jumping multiple times while against them (you should either fix this, by making the ground collision trigger collider of your player smaller so that it does not touch the walls while you're against them, make the walls have a steeper angle so that the player can't climb them, or maybe keep this in the game and add some cool easter eggs at the top of the buildings); also, running and parkouring on top of the buildings was a lot of fun with your floaty jump, so you should probably consider "climbing" buildings an actual mechanic in your game, with maybe some collectibles being on top of buildings.
- Speed up the animations of the game, including the text fading in on the screen,
- Add some immediate feedback for when I press buttons on the main menu (I pressed multiple buttons, multiple times, and nothing happened, so I thought the game was broken or frozen, then after some seconds, I think the scene loaded, and the game started);
- Main menu buttons didn't work for me other than the "Play" button, so I couldn't see the credits not quit the game: if this is a problem of loading the main menu scene properly before having buttons pressable, I'd suggest either adding a loading screen before the game starts or use a black screen to hide the loading of the main menu scene, then fade it out as soon as the scene is loaded;
- Add natural, organic barriers to block the player from going out of bounds instead of using invisible walls, which break the immersion of the game and also make me believe I can go explore somewhere I actually can't;
- I don't know if this is a bug or not, but I had no music nor sound while playing the game (main menu had music, but the game didn't): if no sounds are implemented, I'd obviously suggest to add music, or ambient noises to levels for an even better immersion, plus more sounds to improve player feedback, like footsteps and pickup sounds;
- Specify that you need to pick up mind fragments using "E" also inside the game (since spheres are collected simply by touching them, I thought I had to only touch the mind fragments too, but nothing happened because obviously I actually had to press "E" to pick them up), you never explain how to pickup items inside the game (you never mention pressing "E" to do so), which might confuse some more naive players (like me);
- Level 2 never loaded for me, so I couldn't play it, and that's a shame because I was having fun with the game;
Overall, the game was fun, and I'd like to see it improved and expanded upon, with more levels, mechanics, and a deeper story (as well as adding some music and sounds to the game). Good job to the team!
