Thanks for the feedback!
1. Core idea with the diamonds I had in mind was that yes it is indeed difficult to reach it consistently on first planet, but second planet's unlock requires 15 diamonds and its most common resource is diamonds, so my thought process was that in order to progress further on first planet, you need to unlock second one, to get more diamonds to progress on skill tree.
Maybe this was not properly translated in the game that the second planet would in fact produce plenty of diamonds to keep progressing forwards?
2. I will look into wording for pooling weight skill in the tree so its less confusing, sorry about that!
3. Regarding visual glitch, I am aware of it and have been investigating it, its web-only problem unfortunately only appearing on itch (as when i run the game locally in the browser its not reproducable) so it might take a bit longer to get fixed.
I'd appreciate your thoughts on #1, as it might be something that needs to be reworked / highlighted a bit better. Or I might need to rebalance the skill tree so progressing first planet is doable much quicker (re: making certain skills on the tree cheaper)
