Really an amazing game! It was super fun and the skill tree was a great addition to the gameplay. It gave a sense of progression that a lot of jam games lack.
For some reason, the cheat code was not working for me, so I wasn't able to try out the planet pulverizer, but it was incredibly fun even without that. Also, for the collision bug, you can solve that in a couple of ways (at least just from what I thought of now). First would be to freeze rotations on your rigidbody and rotate via the transform. Or you could have a high angular drag on the rigidbody.
Incredible job on the game!
When you press the "O" key 10 times, it doesn't update the UI but you still have the points, so you just have to click on an ability to unlock it and then update the points you have.
And about the solution for the collision bug - yes, that seems like it would work! Pretty smart!
Thank you so much for playing and commenting, I really appreciate it.
