Nice take on Pokémon! I enjoyed seeing the different types of holes and their abilities. The writing is good, the ending made me chuckle. The music is good, too.
Criticisms:
There's no tutorial, and luckily I read some other comments before playing so I wasn't completely lost.
There's a lot of waiting in the battle scenes, which I wouldn't mind that much if there were progress bars showing when my next turn would be up.
The biggest issue was this bug: Some abilities get locked on and I was only able to use those abilities (though I could use them constantly without breaks). The ash ability lock made it impossible to beat the first boss, and it stayed stuck after respawning at a checkpoint and removing lava hole from party. Teeth was another ability that got locked.
