Nice game, I really enjoyed playing it, the only criticism I have is that for me at least its hard to see with the bright colors blending together, but this is a very minor thing. The game had a really fun puzzle mechanics and it felt really clean!
I'm glad you liked the game! About the enemy speed, we made it so the small dude could run away from most enemies except flies. But because we were on such a time crunch in the end we couldn't really play through the game and balance everything. Hope you still hade an enjoyable experience though!
