This is a cool little game, but I'm pretty sure I've seen a very similar game in a Heartbeast video. Whatever the case, I encourage you to try to make an original game. Certainly a lot of people will rebuild a game in their own style (like the Dr. Mario/Parasite submission), but your game here looks very similar to what I already saw and functions the same way. I think you might have added the figures that run around for you to catch, but that doesn't set your game very much apart from the original. You should definitely keep learning game development, but take a stab at a game of your own design next time. If you work hard at it and don't bite off more than you can chew, I'm sure you can put something cool together.
