Thanks for playing! We actually did think about implementing obstacles pretty much just how you describe, and it was going to be one of the sabotage options, but in the end we scrapped it as the deadline approached. The boost pad skill was taken from there. In the end, I found it a bit hard to balance all the gameplay elements as they interacted together and small changes seemed to greatly affect difficulty (non-linear systems, woot), but I'll take note. I'm sure there must be a simple solution. I'm glad to hear you enjoyed it and that you liked the music and visuals.
