It's been a while since I last made a platformer, so here you go!\n--------------------------------------------------------------------------------------------------------------------------------------------------\nw,a,s,d or arrow keys to move. There are also mobile controls, just tap in the direction you want to go. You can crouch using the s or arrow keys\n\nBackstory:\nA little light cube is lost in a large cave. Help it find its way back to its home, the Crystal City.\n\nFeatures not found in generic platformers.\n-The player glows\n-Animated torches and glowing crystal art (the crystals aren't animated though)\n- Falling rocks\n-Fancy particles\n-If you touch a large falling particle, you will change into the color of that particle.\n\nProject Discussion Forum: https://scratch.mit.edu/discuss/topic/527744/\nGive feedback or suggestions there. :)
