yes thats kinda the name of the game but i really just think that there should be diffuculty changeres. heres some ideas: buff the time upgrade. maybe make it an ability with a 10 second cooldown and it works for 2 seconds and you can activate it by pressing a button or something. the luck upgrade needs a huge buff. make it a higher chance. i would like a upgrade which makes enimies you hit explode or something, that would be so nice. a upgrade that makes it easier to destroy the blocks.
and if you want rougeLITE then you can make some of the destroyed cubes be golden and if you break them you get the currency you can use when you die. then there could be a normal xp upgrade that increases the chances of getting gold cubes. doesnt that sound like a good idea?
im your guy if you run out off ideas. i love these types of games. and my mind can explode with ideas sometimes. so just talk to me when you want ideas :3 :)
