I have been rating by submission order, and this is the first game that I really wanted to play for more than a few minutes.
It would be really nice if there was an explanation of input, what the goal was and what each upgrade did.
Thanks for the Feedback. I'm glad you liked it.
Yeah, one of the learnings that I took from this jam (my first) is that I should put the interface and menu in much earlier. I didn't have much time to work on the menu/interface/help/description.
I put some description for the input on the game page but not on the submission page or the game. It should have been in the game as well.
