Thank you Zyckro for playing my game. Baked Orange said the same thing about the 3 block jumps (I know you said it first), so check my reply to them.
introducing mechanics slowly with tutorials throughout
In the development process the game had only 3 levels, each one exploring 1 or 2 new mechanics. They were similar to the levels 2, 4, and 7 of the final game. I noticed in time that the difficulty spikes were too high and happening too fast, so I duplicated every level and made the transition a bit more smooth for the player.
I tried to do not fall in the trap of “too easy and long tutorials” new games now do. I think is a waste of the player’s time to first go to a “empty hallway” followed by a “empty maze-like hallway” an then a “empty hallway that requires a jump”, etc… You get the idea.
