I had a good time with this entry. I like how much more polished everything is this time around and placing the boosters was a fun toy to mix things up. 

I think 89o is right in that you could tinker with the movement speed and change the system for placing the boosters. Placing them is fun, but doing so could be smoother. One small issue, not even a bug, just a typo. You have North East twice. The bottom one places a North West booster, it's just mislabeled. Didn't mess up my experience or anything. Just sharing in case you hadn't noticed yet.

I really like the movement and little toy as well as that you can place the boosters yourself. I just wish the controls where even a bit more responsive and quick.

The character is a bit slow, but the mechanics are really nice. Both the wall jump and the boosters are lovely, and I really liked that in the playground I can place my own boosters and experiment with them

I'd say this game could be truly fun if only it wasn't so... cumbersome to use. For example, if the character accelerated faster, or if there was an easier way to create boosters, for example by pressing down the left mouse button (making the character not move while you're holding) and then create a booster with the appropriate angle and force depending on where the cursor is once you release the button. Momentum-based gameplay and RGMs with boosters can be really fun, you just have to make it easier to build them in the first place.

This has really surprised me. I don't remember this game from round 1 very well but I had a lot of fun playing with it during this round. The boosters work really well and the ability to place them too, that is simply awesome. I love seeing your blobby like character move around the stage and I can see this game going far
