It's a good base, happy to see the use of the Sly model in a game. Do you plan on adding their tails though? It feels weird seeing them without.
Hoping there will be more of an objective/challenge/threat than simply looking for condoms (ie, a character to hide from, or a time limit to get objectives done).
Also, do you plan on having m/m scenes? Given that it's a space theme, having Fox McCloud and Krystal would be great additions.
