Blerb Tower

This is a short passion project i have been working on for a few months. It is a simple 2d pixel platformer game with the main character being Blerb the bouncing slime trying to ascend The Tower with portals that lead you to unknown locations. Hope you have fun. If you find any bugs, questions or anything to say please say in the comments. 

I am planning on adding a new level and character to the game soon, so keep your eyes peeled.  ^w^

Controls 

Arrow keys = Move

Up Arrow = Jump (hold dowm)

Mouse = Select

1 & 2 = toggle between 2 skins for Blerb

3 & 4 = toggle between background on or off

The last level has a moving platform but you have to wait for it to come down from the top since it starts moving at the start. I am fixing this bug right now.

I might add a better background or add more skins for the character, or add something else if i get more feedback.

PS: does anyone know how to make a repeating brick background that doesn't clash with the colors of the charecter
