This has a lotta promise, but this is definitely still very much in alpha with loads of things that should be refined to make the experience much more enjoyable.
The game tended to crash or freeze a handful of times for me when doing things in the UI, namely when buying several things at the shop and using items on pokemon, but it pretty much happened whenever at any point, leading to me saving after doing anything lmao.
Gameplay overall feels great when the game is working as intended, but the same applies. I'm not sure if it's because of my GPU or if this was experienced by anyone else, but certain attacks I used would also cause the game to stop and softlock which ended up being very frustrating considering the level scaling gets crazy pretty early in. Also some minor tidbits I wanna reccomend are having the "swap pokemon" be the first option when in battle and opening the party. It's the default in normal pokemon games, and helps with the flow of the gameplay. Also, some other small things like knowing if pokemon have abilities or not. Pikachu can paralyze, but I have no clue how to check if it has static or not.
That said, grinding is not that bad, but there are many points where I would enter a wild battle, flee, make an input to move, and instantly run into another battle for about 4-5 times which feels unusual, and also unintended so I feel I should point it out. It helps with grinding though, but is something that should be tweaked considering I will walk out of grass or not even move and run into a battle.
I've only managed to get a handful of grunt battles in, and am not sure how long this demo is, but I think I'll wait on more progress to be made before returning to it. I would love to see this game get more attention and maybe more people on the dev team to ease work as a result because this really can become something special with some more polish gameplay wise. The HD2D look is fully realized here and I LOVE the custom sprites and battle animations. Not sure what the full game intends to be, if there will be one, but good luck to you!
