The most perfect imperfect game I've ever played.

Moment to moment gameplay? Exquisite.
Variation between runs? Endless.
Difficulty? Learn or burn.

My only problem:
Progression takes way too long, and unlocking ~everything~ is not organically achieved by the time you've completed every objective most reasonable players would go for. I like to start a run with a large objective like "beat x to unlock y" where I know that my skill (and a bit of luck) will determine if I can get that unlock. Completing all those macro objectives will leave you starting runs with the goal "kill 25 Lead Maidens" which is not a difficult challenge, just a tedious one. I shouldn't have to rely on RNG to complete a game.
