Nothing too new or interesting describes this about perfectly. "Catch the falling things" as a mini-game has been around forever and this didn't make anything new out of it. I remember having fun with similar mechanics back in Pokemon Stadium 2 in 1999 with Chansey and the eggs. This was relatively slow and boring compared to that and the art was poor; music/sound non-existent.
Congratulations, you remade a classic game and its not glitchy.
But it's a really barebones remake; not remotely unique or interesting.
