Wow, I didn't think anyone would play this game and give me feedback so late after the jam. Thank you very much ^^
As for the bug, I am well aware. The aiming system was rushed for the jam and had a number of issues, so I burned it all to the ground and made a more robust version without this issue, and most other I noticed. I didn't update this game because I didn't think many people would play it anyway ^^'
Maybe I should considering how glaring the bug is x)
For the part about being able to heal enemies, it is an intended mechanic, just like attacking your allies. Though there really insn't much point for the battles in this game, it is supposed to be a fringe yet viable option for some encounters (like when an ally can absorb an element, or the healing mechanic decreasing in effectiveness when used repeatedly, therfore wasting the enemy's recovery with tiny heals)
