I had a hard time completing this game but I managed to get to the end. Good job, really nice entry!
Visually, it reminds me a lot of old Pokemons and Hearthbound, you did a really nice job with the sprites!
I think the game could be even better if the cost and type of moves were displayed. It also lack of sound feedbacks when you chose an option in menus. However it's really enjoyable as it is, so congrats for your entry !
(I really appreciate the Undertale reference at the end)
