Hey there thanks for the feedback.
While I would love for all skill-levels to enjoy my game, I don't think making everything accessible without succeeding in the game is the right way. This would take a part of the reward of succeeding (getting further, seeing new stuff) away from the player. I plan to have a gallery at one point but it will be unlockable with progression (e.g. seeing the enemies you have defeated).
What I will probably add is an easy mode (and hard mode) to the game. But this will be added towards the end of the game and not this early in development, sorry.
The starting deck option might become public, if I have another satisfying reward for my higher tier supporters in the game, currently not planned in the near future.
