Thanks for the awesome feed back!!
Thanks for playing so much! I hope the game will be 10ish hours when it is finished. Yeah the difficulty does ramp up hehe. It's hard to carter to Metroidvania (like Hollow Knight) fans cause they complain if it is too easy hehe. But I will try to make phase 1 of Boss 2 easier for sure, let the player warm up to the fight mechanics. That's a good idea with Boss 1, have the orbiting thing come for phase 2.
Thanks for pointing out that the currency node was hard to see. I'll try adding some glowing particles to it so it stands out for sure :D Later on the melee attack does get damage upgrades~ but I should add more benefit to the melee for sure. There is a seed form heal, upgrade I need to put it in a better place, you can get it before boss 2. I'll be added some NPCs to help point things out in the future too.
Thanks again, I added all the feedback to my notes!
