Here are my initial thoughts after my playthrough:
I really liked your main character, he’s super cute! Did you design him yourself? I also appreciated the “how to play” screen right at the start - super helpful and a great way to ease players in.
I loved that the first level had no time limit, giving players space to explore and learn at their own pace without the threat of the clock. A mini-map could be a nice addition, though, since the environment is quite large and time becomes a factor later on.
Some of the rooms did feel a bit empty - adding more art assets or visual variety could really help break them up. Tooltips near tools would also improve clarity, even if it's just labeled what it is, especially when trying to figure out how and where to use them in later loops.
The “Quit the game in anger” line in the menu made me laugh! That said, I didn’t realize that box was the menu at first - maybe a more distinct visual design would help. Also, changing “Cancel” to “Resume” or “Continue” could make the top button's function clearer as I couldn't tell at first if it would end my game play.
I ran into a bit of trouble using the wrench in the first tutorial loop - it didn’t seem to work when I brought it to the robotic arm, no matter where I stood. I also noticed the player could walk over a few objects, like the engines in the rooms on the far left - might be a layering or collision issue.
Overall, there’s a lot of potential here! I’d love to see you keep building on this with more polish, a deeper narrative, and maybe even different ships to explore. I could definitely see it working well as a mobile game!
