Glad you liked it! Fun fact, the pop noise is a recording of me flicking my cheek 😂. The first bug is known but got introduced and noticed the last day and it felt low priority to get to. The second is intentional, we know the game is difficult and we wanted a way to infinitely upgrade so that anyone could beat it with enough time. Also, it's really fun to get a lot of those upgrades and turn the game speed up. The speed upgrade on your friendly cells is infinite as well.
Anyway, thanks so much for playing!
