Fantastic job with this game! It seems you knew the exact scope of a game you could pull off in the 48 hours, and you took a fair amount of time polishing it and making it feel fun to play. The concept is also a really interesting take on an old genre, and at least for me, it was ridiculously fun to play with. The fact that you can also choose your own skills to match your playstyle also adds a lot to this game. The only thing I could never figure out is what "F" did...
Seriously though, I think I've sunk somewhere between 3-5 hours into this game these last two days. It's well made, challenging but (usually) fair, and a lot of fun to play. Awesome, awesome job with this one!
Also, I tied your record :) http://prntscr.com/15irm6c
