Cute little game, very fun idea. I like the concept of a ricocheting bullet that speeds up after each bounce. The multipliers were fun to chain and get massive combos from, and the different sound effects from positive and negative walls were neat. I think my only qualm is that the game already starts at a high difficulty, instead of introducing the mechanic with simpler levels (I assume that each level is generated and not made by hand). Some of the starting levels felt very difficult to find a proper angle, and even though I bought some upgrades, it didn't help much. I used the laser reflection upgrade the most as it gave insight as to where the ball would go. Overall a neat concept.
