Pretty fun idea, very unpolished execution.
Don't even bother trying to play this to win it. The base exit cost can be reached consistently once you figure out a basic strategy. However, once the game forces you to the higher exit cost, you just need to get really lucky with hitting certain combos.
Probably like one-in-a-hundred chance, ONCE you've figured out the feasible combos.
In addition, there are multiple useless perks (e.g. "Letter X", "Brevity"), multiple that you'd except to combo with each other but don't. and even some with spelling errors ("Speach", lol).
There also isn't much meaningful decision-making/strategizing in here: it boils down to a "push-your-luck" math exercise.
But seeing how this is a free-to-play game in what I assume is pretty early stage of it's life, there is still good potential here, and is pretty good fun for a couple of hours.

(If you are struggling on Monday, here's one basic strategy to pass the basic exit cost levels: just rush to the 99-cost door, even if you need to spend lives and pay time to refresh them. Then just play 99-levels making sure you hit both global reactivations each time, even if you need to spend lives).
