Level Up entered my life
I readed a review where the autor did the same thing as me.
One day I played to Level Up, and played until I finished it 100%. I did my NewGrounds accout for this game.
The pixel-art is simple but effective, the scenario is amazing, we are immersed and near the creator at the same time, there are lot of things that aren't said and that need our imagination.
The game-concept is fresh, the gameplay simple, addictive for the platform game lovers and for the level-upper, multiple possibilities from collect to run or to avoid/fight.
And the medals are good also to keep playing.
It's simple, if you search "level up" on Google, it will be the (of one of the) first result displayed.
