A few enemy ideas
Dragonfly(has a low chance to pick up player and to leave player in random are on map and force a random fight with enemiesof that area *larger then player or maybe have 2 type like a small type that are in groups and a large type where its one strong one that can do the idea above/attached*)
Scorpion(can do poisen dmg and would need a antidote wether bought or made)
Maggots(Found in large groups in swamp so there more variety)
Pillbug(can roll up around the player for players defeat found near rocky area)
Cool idea I had sucking mosquitoe will give effect idk what yo call it but will Increase LP gain for that day unless cured by antidote or removing said bug
