Slaparoo

Slaparoo is a roguelike deckbuilder inspired by the Egyptian Rat Screw card game. You start out with nothing but a normal deck of cards and have to make your way up from level 0 to 100.
Playing Card Mechanics
When you pull cards from your deck and place them your points will increase based on the rank of the cards (1-10). When a match appears you only have a second to slap the cards before they disappear and you lose the points you racked up.
The beginning of a run:

But of course, these cards kind of suck. Your default build won't be adequate for the whole run, so that's where your money comes into play! At the start of every round, you get a few dollars based on what level you just completed and based on how much money you already have (interest). With this money, you can visit the shop and purchase playing card packs.
Picking a playing card from a pack in the shop:

When you buy a pack, you'll have to decide which of the 3 cards presented to you will enhance your run the most. There are 10 ranks and 10 different card seals that each do something unique, whether that be when they're slapped, or placed.
Dice Mechanics
Your dice can be a major part of your run! When you roll your dice, it will eventually land on one of its 6 faces. At the start of your run, you'll have a default sticker on each face, but needless to say, you can use your money at the shop to buy much better stickers!
Rolling the Dice:

Each sticker does something special but most are activated when you get a slap.

Booster Card Mechanics
Out of all items your money can buy, Booster Cards are by far the most important thing to your run. They can lead you to crazy scores, alter your other items, and even warp the rules of the game! As of now, there is a total of 90 unique Booster Cards.
Opening a Booster Card pack in the shop:

Booster cards will activate in order from left to right every time you get a slap, so you have to plan the order in which you equip them for the build you're working towards. If all 5 of your booster card slots are taken up, don't fret! You have a binder where you have space to store plenty of extra cards, and you can equip them at any time.

Equipping cards from the Binder:

This looks amazing, but how do I lose???
When you get a slap, you gain a small amount of HP, and when you miss a slap, or slap when there's no present match, you'll lose a significant amount of health. Run out of HP completely, and it's game over!
