It was pretty fun to play!
Like Ali said, the scene transitions were really nice and it felt really polished + gave me some PS2 nostalgia ;).
For the game design I'd have some suggestions:
- The asteroids and planets were randomized, which didn't really make a lot of sense to me. I had one level in particular where I was constantly dodging them to get towards the sun (and failing to do so, which was a good thing as it where just my first few attempts). But then I just got lucky the next time and could shoot from the starting point to the sun in a straight line because no asteroids where in its way.
- Using the mouse to steer felt overpowered. If I ever had a tricky situation, I'd just shoot myself in the middle of space and go in a straight trajectory towards the sun. You tried to balance it by giving it a limited time, but with no indication of the time left it just felt like the game fucked up or something. I think the game would have been fine without the mouse steering, as you (the level designer) would have more control over how the level would be played
- The idea of having bad gravity nodes is interesting, but I didn't really come across it when playing the game. When I saw a bad node, I just resorted to going around it with the mouse. Maybe you could have placed them in a more 'blocking the path'-way then a 'bad one on the side'-way.
All that said, it's really just some of my thoughts. I liked this game, it was fun to play and felt finished, not just a prototype. Great job!
