Played for almost an hour, got to to level 11 after being stuck on level 2 for a while. The core mechanic is really clever. Placing buffs mid-sim was cool. Art is clean and consistent, and easy on the eyes. Main feedback: a restart button/hotkey would be huge (watching a losing sim after your last buff is placed is painful), and knowing how many levels there are would help motivation. Really impressive how much mileage you got out of a simple concept.
