This healing system seems to be the main target of discussion for this game, and I think I might actually lean towards really liking it. It feels very experimentally awkward and bizarre, but since it's essentially an infinite heal, the jarring atypical feel becomes a strength of sorts to the game. Having to literally change the controlling scheme you're using by frantically transitioning from keyboard to mouse to heal, while having access to only your most basic defensive options as you're healing since the attack is so far away, is a really fascinating bit of meta difficulty. I'm just a fan of seeing new and interesting ideas being presented in the medium no matter how antithetical they are to player convenience so fair play to sticking to such a bold and seemingly controversial creative vision
