It's a pretty alright start for sure, but I do think it's rather lacking in content. There's only three supported characters and each one of them have a single voiceline. Sure, it might be fun to spam them but I rather have a great variety of voicelines than just saying the same one over and over again. Tails in particular has it the worst, considering his only voiceline is a bit too long in comparison to the other two. It'd also be a cute addition to have a little speech bubble or something above you when triggering this.
Nothing that updates can't fix for sure, and I do hope to see some. Welcome Aboard!
