Yo Acaykath, thanks a ton for this massive list! Seriously, this kind of feedback is absolute gold for a solo dev. I quickly fixed the number overflow bug and I'm currently working on the bag mechanics to address your 7th and 10th suggestions.
If you're down to test the new version (I'll leave dev cheats on so you can spawn money and skip the early grind) and break it again before I drop it here, hit me up on Discord! My tag is matte.matico. I'd love to hear your thoughts on the new scaling.
Thanks again for playing and taking the time to write this up!
