Made it to 110! Very fun game, great additions to the 2048 formula
Some notes!
- It won't let me change my name on the leaderboard today, it's stuck as "Player4387".
- It'd make sense to have an open leaderboards button in the game over screen
- You should probably rename the shop from "Item" or add a separate shop button, as it's not clear you need to click on it to open the shop. Maybe you could highlight it and pause the game the first time you get over 150 coins.
- It's not clear you need to trigger the damage / time stop upgrades after buying them. you should just write that in the store or add an explanation for the single use icon.
- Item idea!: An item that removes the ten lowest tiles, or all tiles under 4 or something, as an alternative or replacement to shuffle (I bought it once and got zero new merge opportunities lol)
- It'd be cool if there was a sound effect when you reach important coin milestones for purchasing items. I find myself being inefficient just because I forget to keep an eye on it while I'm 2048ing
- I love the game :D
