Good game concept!!!(Rouge-lite upgrade similar to my game, but you are much better lol). From the start, the sound was too loud, and I can't reduce it. At the first level, I didn't know the enemies would spawn in the middle, soIi died with collisions with enemies a lot (also my last run lol), and from layer 2-3 and so on, the coins drop too much, so I think I just farm 1 enemy box and find 3 treasure. Moreover, when layer 5+ , the coins conceal all the monsters and the bullet, and I couldn't see them and died. btw, I really enjoyed the game. Keep going!!!
