I like the idea of the ammo coming from the enemies, but I didn't understand the multiplier at the top. I think it had to do with the enemies spawned? And I also think that limiting the shooting to such a long timeframe of one second between bullets makes the game seem too difficult to beat because there's no way the player can keep up with that many enemies while waiting so long to shoot. I'm not sure how the out of control aspect is different than other games with enemy hoards, because eventually they get out of control too, so it doesn't seem unique enough. I also found it strange that the player could move so far out of view since there wasn't a border for the playable zone. But congrats on submitting to the game jam! Keep on learning new skills and becoming a better developer! :)
