Fun game, you need 1 important improvement – Work hard, Valkyrie! Review

Game is very fun but please make a way to buy multiple upgrades at once (e.g. 10,100,1000 at a time). I guarantee I will not play the game much longer simply because I have to tap the screen thousands of times to upgrade before each rebirth. Holding the upgrades does not do it fast enough to be worth it. I will change to 5* if this is changed
