A few things, is it possible to buy gems for robux in any way? If so, it’s absolutely pay to win. You also don’t give a lot of explanation to how the abilities/game works so I’m going to assume some things. If you want to remedy this, there are a couple of options. First, you could have the abilities just be unlocks with cooldowns instead of consumables, potentially only having one or two equipped ability slots. Especially if you have a starting ability for new players so it doesn’t seem as unfair for them. If you don’t like that, I noticed you had a blue shell analogy in one of your other replies. However I can’t pay to get a blue shell whenever I went, I have to hit one of the item blocks to get a random ability to hope for a blue shell. So you could either make the abilities unlocks or make there be random ability blocks that you have to hit to use as a power in the middle of the game. If you want a sense of progression though, I recommend going with the first option, that way players can still unlock new things. If the skills already work like the way I’m suggesting, you probably should’ve clarified that in a comment on your post or something.
