I've spent 30 hours over a week and a half playing Hades. It was nearly impossible for me to put it down to do any editing at all. There's still whole aspects of the game that I haven't unlocked yet - Pets - Some Hidden Aspects - but I wanted to tell you about my experience. I've added a few things that I wish I knew going in!
Hellver is a Downwell-like with a 3D spin on things. This is an early development build, but early access in in the near future. If you're into precision movement and physics based momentum, this is a great basic shooter for you. I've had a great time playing and hope to stay up to date with the development. Come check out the discord, the lead developer is very engaged with the community!
