Thank you for the great feedback!
In the future I want to add a lot of items, but you will be able to use only 6 at once. That means that you'll be able to enable/disable the items. That will emphasis a deckbuilding aspect (a genre that I have more knowledge) while keeping the incremental dopamine.
I also want items to be unlockable based on certain conditions.
Yes I added the game jam version in the download :p
That sounds fun. If you want to limit the items at only 6, I would probably make it so the player can chose 1 in the beginning (that they want from the ones that they have unlocked (so ones they have bought in the deck).
I'm very interested in how this will turn out.
One question tho: what do you think you will price the game? So i can save up for when it releases.
