It's too tedious and boring. There are few chips, they give little. Upgrades give little and the effect is almost invisible. I played for an hour and a half, and nothing changed. I haven't seen a single boss, and there aren't any new mechanics.
I rebalanced the upgrade effects to be more noticeable. Bosses typically spawn at 180 seconds in.
You'll see the boss at 3 minutes in a run. Which can be reached and beaten with the difficulty reduction, armor upgrade, damage and critical chance.
It is a very slow, monotonous game though and the stuff you get with prestige isn't that useful.
