The shop refreshed once, at level 15, and that was it, so I always had an excess of coins and the sell option in the shop was never useful. Although, it doesn't matter because after like 5 minutes it got boringly easy.
It glitched, so it doesn't show my level anymore, but I'm probably around like 28. All my stats are above 220, so for a while I've just been holding down click and moving forward; there's no need to dodge or aim. I could be aiming backwards and I'd still instantly kill everything; all those bullets cause increasing lag.
There's no end to this, so imma just quit.
Since nearly every red enemy shot just insta-kills, or nearly insta-kills, the Max Life stat is pretty useless, and I don't even know what Defence does.
One time it glitched, I guess while loading, so I had negative health and I was immortal until I got to the shop; I was riding the sliding dice like a roomba.
