Really fun idea! I'm not sure if the slipper movement is more of a hindrance than a feature. With some tuning, I think it could be something really fun!

A really fun idea, I love how the blocks slam down into the ground. Really startled me the first time! If you were to continue working on this, I'd adjust the slippery handling.

The music is very great.The idea of turning tetris in to a uncontrollable game really fits the theme. the only problem I had has that running felt like running on ice. but overall it was a really great game. If you like you could check out my game on https://itch.io/jam/gmtk-2020/rate/698144

TRY PUTTING THIS IN TO THE CHARACTER CONTROLLER

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class player : MonoBehaviour
{

    private Rigidbody2D rigidbody;

    public float stopspeed = 1f;

    float timeLeftToStopRunning;

    float HorizontalInput;

    private void Awake()
    {
        rigidbody = GetComponent<Rigidbody2D>();

        timeLeftToStopRunning = stopspeed;

    }

    void Update()
    {
        HorizontalInput = Input.GetAxisRaw("Horizontal");

    }

    private void FixedUpdate()
    {

        if (HorizontalInput == 0f)
        {

            if (timeLeftToStopRunning > 0f)
            {

                timeLeftToStopRunning -= Time.deltaTime;

           }

            if (rigidbody.velocity.x > timeLeftToStopRunning || rigidbody.velocity.x < timeLeftToStopRunning * -1)
            {

                rigidbody.velocity = new Vector2(timeLeftToStopRunning * transform.right.x, rigidbody.velocity.y);

            }

        }
        else
        {

            timeLeftToStopRunning = stopspeed;

        }

Really good game based on fresh combination of two game mechanics (tetris + platformer). I liked to play this game.

This game makes me go YES! Super creative!

I think this is a super creative idea and I would love to see a fully developed version of this game, but I had a big problem with the slippery movement and also the fact that speeding up is instant instead of also being slippery. These things together make it impossible to have precise movement which is kind of required for this type of game and ultimately kind of ruined the experience. I can understand if it was done for the purpose of fitting the theme but I just don't think it worked out. Otherwise, the presentation is really nice and I love the way the blocks slam into the ground when they get placed, so good job on that! Give my game a try too :)

Fun idea! I did get stuck inside a single open space, however. Might be nice if the hit box size was the size of 1 segment of a tetromino so you could fit through tight squeezes. I felt the controls were too slippery so it was too hard to just move over one segment length. I wish there was some more telegraphing that the pieces were about to go into slam-mode so I could plan a bit more.

Overall, a neat idea that I wanted to play more. Definitely worthy of post-jam pursuits!

Neat game,on my last try I got cagged and couldn't jump far enough, maybe something like a wall slide mechanic could improve the gameplay.

Man I really like the game idea, but to me the slippery controls just make it so frustrating.  If this choice was driven by the out of control theme, you should concider updating that after the jam. Because then I could see this game being much fun, Great work!

Really liked the game. The only problem was the controls. Though other than that a good idea and an enjoyable game. Well done.

This was fun and it was a good challenge with how slippery the player was. Good job!

Like the idea but agree with other commenters that controls need to be tighter for a game like this 

This is fun since 3 days before the theme is official I was thinking "Whatever the theme I will make a tetris-like game around this theme", I changed my mind but you did it and you did it great ! I love the concept, the game has a  lot of potential, if the hero can push right or left some blocks of some colors it could be very strategic. I think the game is hard enough, adding the slippery control made it a little bit too hard for me. But great idea, I think you can do so much more with this game with more time. It's strange that blocks almost never go far left or far right. But anyway, congratulation, nice job  !

Sooo satisfying when blocks land on the beat drop.

Game looks absolutely phenomenal.  I love the way the Tetris blocks are animated as they fall, the way they pause and then slam down.  Most frustratingly though, the character is very very slippery.  That seems to be intentional to give the game a more out of control feeling, but it makes an already hard game significantly harder, and it does make it somewhat less fun to play.

Liked the concept, wasn't a fan of the "slippery" controls
