Always interesting to see more of these transformation games crop up since AI generation become more consistant. Although I would give it more credit if it was made by an actual artist, I can understand there's likely a considerable amount of alternative character art planned.
Gameplay wise, it's a bit static but I can see that figuring out attack and defence block placements certainly gives it potential. I figured there could be some interesting gameplay with using block against overpowered enemy attacks, but once I crafted a Split that I could use every 'x-0.05' seconds, I more or less steamrolled everything.
2 notable bugs I noticed through my playthrough (0.1.6.1.)
-Messing with the speed at the end of defeating an enemy can allow you to defeat them twice, giving you two defeat dialogs and loot windows.
-Sometimes, there's a red '22122' square that will spawn that will crash the game if you click it. I've only noticed it appear on 4x speed so it usuallycatches me offguard.

I'll be interested to see how much you plan in regards to expanding on the story and progression or even just more options with ally characters.
