I have no idea how nobody has commented on this yet or how it only has 2 ratings so far. Thats criminal! I like the theme you were going for - lost in space, needing to get back home - I love this kind of art style!! Pixel art has developed into my favourite form of game art so I appreciate it and the effort. Nice music as well. Some constructive feedback:
- When I build a Carbonex miner it actually says that its Ferosite miner and its confusing because it says it needs Ferosite to upgrade but then deducts Carbonex. So we're probably just looking for a variable of this prefab to be setup to kill that bug.
- Once you setup your miners there isn't much to do other than run around and collect some more minerals while you wait for your miners to do their work. Obviously game jam time limits what you are able to implement but the theme is so good that you have options here - maybe a meteor shower that happens every so often, aliens that scan for life and you need to hide, and a game timer that runs down until you run out of oxygen and die, forcing you to make critical choices around whether you decide to harvest and store resources, or spend them to get more resources, while avoiding the threat of meteor damage and aliens etc.
- A full screen button would be amazing for this game.
You art style is on point, the aesthetics are great, the mechanics are solid - this is simple but its fun with loads of scope to build on. Great job.
