Interesting idea! I actually had more fun than I thought I would, as It has some addictive qualities. I did start to wish for more upgrades after a level or two, but overall good job!
I think combining numbers growing and the possibility of gambling them is always adictive hahaha
I wanted to add roguelite-like modifiers after each screen ( like Nuclear Throne ) but it was too much for 3 days of work
Thanks Yah'el! 😀
