Thank you so much for playing.
All really good points, most of them come down to that I had an idea on how to solve it but didn't have enough time. The number system is actually the most common system I've come across, just ahead of K,M,B,AA,BB,.. I had initially planned for actual names K,M,B,T,Qd,Qn,... but I had space constraint issues and I intended for the numbers to get into the UnD range but that ended up not working; so in hindsight I would have gone back and done full names.
Tab buttons should have shown if they were active, and if I had formulated a full plan of the science and satellite tabs I could have made it less intuitively confusing. Fun fact the science tab is internally called the satellite tab, and satellite tab is internally the moons tab - their roles shifted and merged a little which happened from time constraint getting it done.
What do you mean by hover effects for the tabs?
I neglected to realise that the small screen when testing was different to small screen on web and overlooked the issue, I was completely blind to it being an issue as I just assumed it was the same and while I did complete the game on web I had it full screen. Something I'm aware of for the future.
I wanted to add progress saving but I didn't structure my data in a way that made it easy to save - of all things it would have also required me to remake how music works, if I had been in the mindset that I needed saving early on I could have probably done it but I didn't expect it to be a requirement and lowered the priority. This game is a big learning process.
I hadn't anticipated an issue with science, you earn science every time Earth or a satellite (natural or artificial) orbits - Earth around the sun, satellite around their body. Upgrading science per orbit affects everything, upgrading satellites for a planet increases the permanent boost granted to the planet - get more satellites and upgrade them and you can end up with multipliers in the hundreds. I had actually balanced the game around people using science fully otherwise planets like Mercury earn nothing. In the future I'm going to have to add in guides for everything even if I think it makes sense.
I had intended for there to be dwarf planets to buy with black holes and I was going to have a win condition once you buy the entire solar system but I had to drop that because of time and so no win condition.
This game has so much packed into it even though it doesn't look like a lot, soaked up all of my time for these extras. I would love to revisit this game some time, it would also be a really good first 3D game to make, and I can make it fit the vision I had for it fully.
