It’s a cool mix of different types. Most are active skills (select where and when to use them) which either have a cooldown (e.g. fireball: 5 turns) or have a fixed number of uses per level (e.g. stopwatch: 3 per level).
Others are passive skills (always taking effect) - such as the ability to smash walls, or find more gems per level.
Hopefully, many of them synergize well with others - such as the combination of both proximity and time bombs (bomberman?); or the ability to melee-stun enemies and drain health (vampire?)
