Always good to see new developers not being afraid to jump right into a gamejam even if they are inexperienced. The point is to have fun so Im glad to hear that you did! I think the main thing this game could use a bit more of a difficulty curve and maybe some particle effects or animations for when the slime falls down the hole. I'm also not sure the music is very fitting for the type of game that this is. But otherwise it's pretty good so good job making this! Please give my game a try too :)

Hey, loved your game,  loved your art , music , game design ,a bit of polish and your game will be pretty cool! I enjoyed playing it. 
All the best and Good luck! Do check out our game we need the feedback! - https://itch.io/jam/brackeys-3/rate/574293

Nice atmosphere, nice sounds and music! :) Like @nightworks said, it would be really nice to have a shop system to spend the coins but all in all a really good and fun game. :)

I would really appreciate it if you could rate my game too. :)

I really enjoyed the epic atmosphere! This is a solid game that has many ways to expand, if you're looking into it, such as adding a timer to have high scores or even a shop to spend those coins on. Still, really solid work!

Cool game, had a lot of fun playing it. The only problem I had is, sometimes the coins spawned under the holes. Other than that, it's awesome

Nice entry. I really like the athmosphere of the game. The music really fits the "greyness" of the game.

Controls felt bit janky at times and the overall game could do with some polish. Other than that it's a good start.

Cool game, i had some issues with coins spawning in the holes, other than that nice job.

Very nice game. At first I had no idea I was moving so maybe a texture  on the ground would fix it. The game was pretty fun. Good work!

Simple but fun game. With a little bit more polishing on the controls, that can be great work.

Maybe you can add some more features, also you should work on smoother player movement, it jiggles a little bit.
