The idea is nice, however you are so heavily reliant on RNG, that I got two pink blocks that marched from the very left to the end, without me getting any pink bullets. You should force the game to produce one of each color at least once every X spawns. This would make the game even better I think.

very harmonious and well playable game. However, I lack the ability to react to all of these random events (especially the colors of the cartridges can make a big difference that you can hardly influence). This gives me the feeling that it makes little difference whether I play the game actively or just watch it.

Wow, your game is fun ! I got a score of 100 x) The art is colorful and well designed ! I’m colorblind so I’ve some difficulty to see what’s the color of the bullets. The game don’t totally fit the theme, however, but has a cool conept ^^
