Glad you enjoyed the game! I agree that it is a rough start when learning the game, but we wanted to give that fast paced feeling. For art and animations, we were on a time crunch implementing the art and had to cut the animations for the sake of getting this done.
Really glad you enjoyed the game! I am sorry to hear that you encountered a bug. Around the 2 minute mark the game ends and a function is executed running endgame code, there may have been a one off error running that code so maybe try again and see if it still persists.
