I love these kind of puzzle platformers where different characters have different abilities, and your characters are super cute! I did run into a few issues though.
With the red character, I found it really difficult to know which way I was charging up. It'd really help if there was some kind of direction indicator to let me know my input is correct. The instruction on how to launch was a bit vague so I had to guess (you drag the mouse in the opposite direction, right? but I can't see the mouse). Also there didn't seem to be any explanation on how to use blue abilities, but I tried everything until it did something.
Some of the time that I pressed buttons it didn't do anything and I had to restart the level. I played through the game twice and both times got stuck on this level after pressing both the buttons, which was a shame because I really wanted to play more! Was I doing something wrong?
I love the design of this, it just needs those few bugs ironing out.
