Far, far too grindy in design. This needs more story and less 'kill over and over to gain xp' in its design. It feels very padded and same same as a consequence. Which is a shame because there is something great at the core.
For future reference, grinding monsters over and over =/= good content.
Lack of a level select means I can't vote this one low enough at the moment. A simple miss-click into 'new game' can wipe your entire progress.
Additionally, sort out your checkpoints, they're pretty frustrating at the moment for a game with these kind of hit boxes.
If you are going to make a miniseries out of this, please remove the minigames. I am just spamming attack now because it is the least tedious and irritating of the options.
