This is an ambitious project with a large-scale idea: managing an energy station, generating power, collecting resources across the Solar System, upgrading systems, controlling a character, and playing a timing-based mini-game. It is clear that you tried to include many different mechanics and layers, which is especially impressive for a first project and first game jam.
Unfortunately, the current experience feels quite slow and difficult to enjoy. The main issue is that there is no clear visible goal explaining what the player is ultimately working toward. The progression also feels balanced for a much longer game, while jam players may only spend around 5–10 minutes with a project. Upgrades take too long to reach, so progression quickly becomes repetitive rather than rewarding.
There are also several usability and technical issues. Some UI elements overlap or interfere with each other. I couldn’t find a clear summary of how many resources I currently had, even though resources are required for upgrades. I also couldn’t understand why I was unable to land on some planets—perhaps there is an energy requirement, but I couldn’t find that information. The energy counter can also go below zero; simply clamping the value to zero would make it feel cleaner.
With clearer goals, faster progression, better balancing, more informative UI, and some technical polishing, the core idea could become much more engaging. I understand how difficult it is to implement so many systems during a jam, and I mention these issues only because I hope they may help you improve future projects.
I also have two small suggestions for the Itch page:
First, I recommend disabling Itch’s fullscreen button in the game settings. The Unity WebGL build already includes its own fullscreen button, and the additional Itch button overlaps with it and makes fullscreen mode less convenient.
Second, consider increasing the viewport height slightly. Unity WebGL adds an extra bottom bar, so using the exact height of the game resolution can cause part of the game to be cut off. For example, for a 1280×720 build, I usually use approximately 1280×770 on Itch.
Sorry if this is a lot of feedback. These are only suggestions, and you should decide for yourselves which ones are useful. Most importantly, congratulations on participating in your first jam and completing such an ambitious project. You did a lot of work, and I hope you continue making games and improving with every new project.
