This is a ridiculous amount of amazing art to make in 48 hours. The game loop is also pretty solid, but some variety is needed to retain player attention. I dealt with 6, then 5, then 4 Pokemon all at once, all suffering from the same status effects and I saw the same sprites, and somehow my Hyper Potions disappeared (but that's excusable, I didn't need them).
With the same assets, you could probably distribute the difficulty to make a level curve. Start off with Pokemon without statuses, then introduce statuses, then begin restricting the time limit. If you're aware of Diner Dash, perhaps there might have been a way to incorporate the queue system from that game.
Otherwise it's really cute and really fun, and I'm glad I got to play it.
