Thank you for your comment! I am glad you appreciated the way new stuff gets introduced. I've been realizing now though that the bad part of doing that is that now most people that play this game don't ever see that stuff :/
Yeah that's definitely something to take into consideration. If this was a full game it would be expected that new stuff would be introduced slowly, but game jams have different rules. This would definitely work as a full game with some more time to balance levels and design some new mechanics.
