A great concept! Like a platformer getting over it.

Congratulations on your first game/game jam! -- You did an excellent job. The controls felt quite good, and the hold jump was an excellent extra feature. I liked the graphics - Simple which is how I do it. I really really enjoyed the particles at the player's feet -- It added a good amount of polish. It would have been nice to have some background audio, but I know what it is like to be in a rush. :) Fantastic job & Keep it up!

Really impressive first game! Really liked the controls and level in general and the game was relatively well polished overall. Having a pause menu is great too, love to see it!

Just some general feedback:

• Remember the player doesn't know the level like you do, so with the invisible platforms that have differing sizes, it might have been cool to highlight them somehow once you'd landed on them... Falling off just because  you don't know the size of the platforms can kind of be disheartening
• Take a look at Unity's post processing stack. Once it's setup it's an easy way to take the visuals of your game just that tiny bit better!
• In most cases, try to be consistent with the size of your pixels in the game, use the "pixels per unit" property in the Unity texture field to help with this. That consitency often helps just bring the visuals a bit more together
• Music, even some NCS bits you found online can be very nice, even just in the menu
• Unity also has a platform component that allows you to jump up through the bottom of a platform but stand on the top, could make for some fun gameplay?

Overall really nice little game, quite enjoyed it and the fact it's your first game makes it all the more impressive, fantastic work mate!

I often find it useful to watch how players interact with my games I play, so I recorded the gameplay in a quick video if you'd like to check it out :)

Promising first game jam entry 💪

GAMEPLAY

I read the slippery was intended, but it made it more difficult to progress. It was also an extra challenge. Had fun playing it and for a first game jam entry it was not bad at all.

GRAPHICS/ART 
Own made graphics is always cool! Read that you could do even better so like to see that in a next jam 😊!

AUDIO 
Jump Sfx was nice, but a background track would have been a good addition to the game and the ambiance

THEME  
I think that it could have been something more present.

Keep up this good work in you next game projects and jams!💪

The control of the character felt slippery, but at the same time, you could jump between many platforms in a smooth flow, which was very satisfying.

Sometimes, the level design felt confusing. Having someone to playtest would probably have highlighted this.

But overall, good work. Congratulations on making your first game!

The game has potential of being a cool frustrating challenging 2D platformer, but it is very lackluster and kinda unfair at times with its floaty movement... but for a first game it gives promising insight into your future projects if continue learning and making games!
