Once you reach level 40 you max out the number of upgrade slots, not to mention certain stats like speed, jump height, and cooldown reduction are all maxed out despite not being that much of an increase (cooldown reduction only goes to +12%). I feel like you should keep earning upgrade slots to at least 30 or 40 points, and I think that certain stats like Speed and Cooldown Reduction should definetly get their maximum caps increased to at least +50%.
Same with Joker Slots. Once you reach level 50 you've maxed out the number of Joker Slots, but because good cards costs 4-5 slots, it means that you can only really have a maximum of 3 cards. Personally I don't feel like that is nearly enough to make any interesting joker combos or builds that synergize with eachother. I'd want to see an increase of the maximum Joker Slots to at least 20. This would allow you to have 4 good cards in your build.
I'm also bummed that certain cards like Giant and Dwarf are unpurchasable and can only be found in the game. I feel like every single Joker that exist should be purchasable in the Joker shop or using the gamba machine.
The complete pause on progression at a certain point makes game, that was initially really fun, feel way less rewarding. I do understand that restrictions makes each build more unique, but I don't feel like the current maximum allows nearly enough of a high power-level to make truly fun builds. If the game needs more harder difficulties to allow for this, then just add it. That should not be a reason to severely cripple progression and hinder truly unique builds.
