Stack Attack!!

My game gets stuck on thr second diamond on level 38. The challenges say to check out the shop but there is none to go to. I thought I could get to it after level 50 or whenever the end of the 4th world is, but it gets stuck at level 38. Since I get 100k coins each time could you add a way to quickly level up the weapons, im getting tired of spending 80 coins at a time and just holding yhr button for eternity.

A fun little game. Buggy and unplayable suddenly. I played a bit last night, got up to stage 4 or so. Opened it up this morning and I'd been sent back down to stage 1. Got the Uzi upgrade and instead of damaging the blocks, it adds to them. Hoping this is fixed soon. I was enjoying this game.

At first, the game was appealing. After you pass the low league as always it's a spam of ads to get something decent. The game jumps twofold in some levels in which you are limited in options with paths to take. The weapons aren't all made equal as some are actually overpowered as hell, and some are as useful as a paper. In the end, the game is fun, but to progress with damage and level ups makes it a long term game. Also it doesn't save gems which is ridiculous if it gives it for free.
