It was very fun to launch an attack.
I was first very confused how to get past the doors. I think door unlocking should be managed somehow different. Not sure if it is really needed that you unlock that way. Either way it was good mechanigs that you can upgrade the dice.
Like you have written graphigs needs update. Otherwise everyhting had purpose and worked to show what it was.
I also had the mouse clicking bug. Needed to figure out on to fly how to attack when you cannot click here or there.
I feel like the attacking could have multiple hits when it bounces. Now i think it had only one attack from the first hit.
Nice game!
