I really like the core mechanic of pulling the orbs in and then timing a hit to use them as projectiles. Chaining a bunch of these together felt pretty satisfying.
However, sometimes I found it hard to judge the distance at which you could hit something from. This was especially apparent when trying to melee enemies directly. It sometimes felt inconsistent, which I think is due to having no visual response from enemies when hit. There is also the issue of enemies not really telegraphing when they attack. I found myself unsure if they actually were attacking me or if I simply took damage from touching them.
I think the idea is really cool, and overall was pretty fun to play. I think the game could just use a bit of polish in terms of visual response from enemies.
Well done!
