Ascent is a combat-focused rush of trainer battles with roguelike-inspired progression. The gameplay loop lacks the adventure side of the normal pokemon experience, in favor of refined competitive battles. You start at the bottom of the tower with three starter pokemon and progressively make your way from floor to floor, earning currency to upgrade pokemon and items. Each floor has a variety of quality-of-life features to get your team ready for the next gauntlet without the regular headache of grinding. See if you have what it takes to ascend to the top!


  • Every floor has unique battles which must be completed in sequence to progress
  • Losing resets the floor battles. The flow is: prep->complete all battles without a pause->progress to the next floor
  • Alternating single/double battle floors
  • Rotating trainer teams. Trainers have additional pokemon and may switch them out randomly between attempts. Operates on a slot-by-slot basis.
  • All pokemon up to gen 8
  • Mostly up to gen 7/8 battle mechanics, items, moves, abilities, with some adjustments and additions.
  • 3 different currency rewards at the end of each floor.

  • 3 difficulty settings that adjust ev/iv amounts for trainers.
  • No bag used in battle.
  • No money loss on lost battle.
  • Forced set mode.
  • Held items restored between battles.
  • All of the player’s pokemon have perfect IVs and always start with ability 1.

  • Room battle hints. Talk to the trainers on each floor for a small amount of information regarding their strategy.
  • Bag sort

  • ~20 custom abilities, some may not be on any available pokes yet though.
  • ~5 custom items
