So simple but fun It would have been better if there was a checkpoint.
Viewing post in Bushko: in factory jam comments
I had a doubt about checkpoint because of time spent playing. I haven't enough time to make a lot of content so I didn't add checkpoints for game to last longer because you need to start all over again. My initial idea was to have two levels and then there would be checkpoints but for time of this jam I restricted it to 1 level and boss. There will be post-jam version with more levels.
