Hey nice game! I liked it!
I like the gameplay and the rogue-lite aspect of dying and returning stronger. I also liked the relaxing and soothing music. Lastly the visuals were nice!
I do have some small feedback. It was initially for me not that clear that you needed to collect the orbs that enemies drop, making my first few runs a little confusing. Also I do not understand some parts of the mechanics: why your health decreases even when you shoot and what the Aura upgrade does. I feel like all these things could be solved with either a tutorial or little more information in the description.
Anyway these are just my suggestions, it was a very fun game to play!
Cheers!
