Nice game but takes way too long to grind.
Just an fyi for others: the most efficient way is to spam the thing that looks like a tail (it gives the most), immediately spend the dice and then just reset by going past her limit. Its way faster than waiting for her to sleep and refresh the heart (your progress saves after each purchase, so if you are doing this remember to buy stuff before the reset)
If you do plan on updating this:
Having an option to choose which of the 3 unlocked training scenes play would be nice. I got the 3rd one for the whip and literally thought it bugged out because i didn't see the 3rd scene even after spamming that event. I only saw it once when grinding dice after beating the game, way after i thought a 3rd scene didn't exist for it.
And like i said at the start, too grindy. I ended up not unlocking everything because it became too monotonous
