This is a fun concept for a platformer, I'd be interested to see what you can do with this. I couldn't get past the second level, couldn't find splashy anywhere. Physics felt okay, maybe a little rigid, it's hard to describe but didn't feel super smooth. SFX are okay, the song was a little repetitive but not bad. I thought the puzzles were okay, I think the potential for puzzles with the multiple different characters could be great. Finally the spikes were hard to see, I kept running into them without even seeing them, they could use a little more visual clarity.
