Really cool concept, chill vibes and relaxing gameplay. I like how the ships are different, and aren't a simple upgrade, you still need the first ship in later maps. Keen to see more maps!

Thanks for the lovely feedback, glad you enjoyed the game!

hey again, did some gaming for ya!

--start of report--

logs still give null reference errors-

on lag, audio will stutter. example: load into an area on a device that has a moderately strength cpu and a slow disk r/w speed

music has a bad loop

game window does not fit screen- see image

controls do not adapt to active controller- see image (the image is dark because I was paused)

on scan, game fills log with many repetitions of-

BaseToolUIComponent.UpdateFromToolData called on ScannerUIComponent

NotifyUIStateChanged from ScannerTool, subscriber count: 1

during me finding out how the gravwell works, my game froze for a moment. no errors in log.

gravwell also overfills log-

BaseToolUIComponent.UpdateFromToolData called on GravWellUIComponent

wasChargingPrev: True _isCharging: True gwData.IsPulling: False

NotifyUIStateChanged from GravWell, subscriber count: 2

GravWell: chargeLevel 0.20555557

when I first put scrap into the salvage ship, it loaded a bunch of code and froze my game for a moment-

Salvage Debug - Mass: 1.0kg (Small: True), ValuePerMass: 175, BaseValue: 175, EffectiveValue: 175, Efficiency: 100.0%

Salvage Debug - Mass: 1.0kg (Small: True), ValuePerMass: 75, BaseValue: 75, EffectiveValue: 75, Efficiency: 100.0%

there is no tutorial :(

---end of report--

I had to stop here, as I was hungry and the laptop's battery was low. will continue later!

edit- also noticed that it uses Godot's icon for its icon

Logs aren’t a gameplay feature I’m not even sure why you’re seeing them. None of the logs are problematic or showing issues that are game breaking, they’re just debug logs. This discussion might best had in our discord.

Cat_45138 days ago

run the game with terminal! (cd path/to/folder and ./game.exe)

also, you don't provide a discord link anywhere :p

since I'm not having many game-breaking bugs, I could give you some recommendations on how to make it better.

Happy to hear any feedback, I’ve just added the server to the description, here’s a link: https://discord.gg/cQnXFa7fVq

Awesome little space scrapping simulator game. Really chill game with no pressure, and a great progression system that really leaves you wanting 1 more round.

Rohan Moon137 days ago

Love to hear it!

Cat_45139 days ago(-2)

Wasn't able to get into the game (chromebook with no gpu trying to run linux which is not optimized for cpu) but I did catch some errors in the terminal for ya before it crashed!

I'll try again later once I get the replacement SSD for my PC (a windows update was put out that killed all SSDs of its type, yay...)

Maybe the problem was the fact it immediately set shadows to high? idk I can barely code.

Rohan Moon139 days ago

Hi thank you so much for reporting the error and including your log! I’m sorry to hear about your PC. I’m going to look into this issue now and see if I can solve it, though even if I do I’m doubtful the game will run very well on your laptop. Maybe we can find out.

Cat_45139 days ago

(I made this before you said about the graphics driver. can't update it anyways cause, y'know, chrome. imma see if I can run it on my old win laptop tommorow)
I don't really need to be able to run stuff on this thing, I'm mostly just messing around and seeing what it can do. After all, simply watching videos on Firefox makes this idle at ~60% CPU and 50℃, as well as glitchy windows and stutters (more below)

Hopefully windows restore will be able to get my PC back online once the replacement SSD comes, then I'll be glad to help you with error reporting 'cause this seems like a cool game.

More about Chromebook CX5501FE:

"Gaming" they made WASD red

Dual hinge! Now you can have the biggest of tablets!

Can't seem to enable screensaver

Lowest fan speed still is very audible

Such a hassle to install a bootable linux OS (I gave up lol)

Want to have a windowed app? say hi to hell:

I ran Polytrack on both firefox and chrome, side-by-side, and FF was running horribly while chrome was smooth

Rohan Moon139 days ago (1 edit)

From what I can tell, the first error was unrelated, and it can actually recover from that, but the second error “LLVM ERROR” is a linux driver issue, and I doubt there’s anything I can do about it. Try updating your graphics drivers!

SovereignHarbinger141 days ago(-1)

textures are borked, cant see ship, fuel station nor salvage

Rohan Moon141 days ago

Hi thanks for letting me know about the issue, I’d love to be able to fix it. Could you give me some information on your computer, and include a screenshot of the issue? It would help to know your operating system, and details on your hardware to help narrow down the cause.

SovereignHarbinger110 days ago

sorry for the late reply, i forgot i made a comment to begin with. here is a screenshot of what i see in game. the black pixel is a bugged texture. here is a second picture,

OS: Windows 11

CPU: AMD Ryzen 9 3900XT 12 core

RAM: 32GB

GPU: AMD Radeon RX 5700 XT

please let me know if you require more data and i will try to give it (i took these at the time of writing this)
