Hi! I tested you games current version and here's is some of my thoughts after playing:
- I like the multiplayer star background. It's very atmospheric. Although I think there is some issues when turning. This is especially easy to see when going in circles. If try pressing up and down at the same time for some seconds you should see that the stars start to move chaotically.
- Also other visual element of the game looked really good. Great job with this!
- Moving up or down I feel I don't see where I'm going because the spaceship gets so close to the edge of the screen. Maybe the camera could react faster when moving vertically. When moving left or right the camera movement is fine.
- If there was a goal in the current version, I did not find it. I noticed that one can shoot asteroids and collect rewards when asteroid is destroyed but this did not lead to anything. I guess I got points from doing that but as there was no way to see how many points I had collected it did not feel like I was making any progress. You might want to add having an UI with total collected money to your to do list.
- The money/score gained from one item was quite high to the point that it was really hard to read the whole number and understand how large it was before it disappeared. You could consider having slightly lower values to make it more easy to the eye. I think values with 4-6 numbers are still recognizable but after that it starts becoming difficult (at least for me). Another option to improve readability of the values would be to use commas or spaces to break down the values: 123 456 789 or 123,456,789 are easier to recognize than 123456789.
- Otherwise it was good that you had those numbers popping up when collecting the items. That's making it very clear to player that they gain something and flashing big green numbers on the screen can also feel rewarding.
- I was expecting that hitting an asteroid would lose the game but then it did not happen when I accidently bumbed into one. I can see that you have mentioned ship damage in your future plans so you have probably thought about this but the game should definitely have some way of losing. Or at least most games have something like that.
- About the controls: personally I would like the spaceship to have bit higher maximum speed and have it be able to change direction bit faster. Now turning feels bit slow. Unless you would specifically have meant the controls to part of the challenge or have the spaceship to behave with very "realistic" physics (=fast object changing direction slowly), I would encourage you to improve controllability of the spaceship. In many cases the game becomes more fun when things react to user input quickly.
Hopefully at least some of my feedback is useful when you are continuing with your project. Good luck!
