I do recognise that this game is probably bugged, but hey, having a submission is better than none, the purpose of the jam is just to inspire people to try and make things. Even if you fail this time you still learnt something you can apply elsewhere.
Here's some feedback pre-game break:
- Hiding the upgrades when they are not bought is probably a bad idea, as you often want to see the effects of them.
- A formatting function: at some point you have 0.30000000000000004 black holes. Floating point errors are inevitable so it's a good idea generally to account for them.
- Layout-wise: The huge screen size and small hitbox of celestial bodies makes things awkward. The upgrades should probably be placed close to the celestial bodies, instead of far away. Highlighting the planet whose upgrades you're viewing would be nice as well
- Gameplay-wise: The active clicking of planets and idle nature of stars without really anything to connect the 2 makes for a very odd contrast and disconnected feeling, which could be improved
