Cool game and i have some ideas:
First: Fix the lag {if its in the full game}
Second: maybe add some endings like secrets treats that you need to find for a secret ending?
Third: sound effects and maybe an instruction manual if people download it and don't know the controls especially for new player who havent heard of this
fourth: Maybe add a customizer
Names of endings: Bingus ending: collect secret binguses around the map. Nyan cat ending: you need 2 endings so you can see the portal to nyan cat's world. Normal ending: complete quests and thats it. Chrome ending: go to the browse game. lastly the rarest one My cat stepped on a bee: need to have 3 endings to unlock this ending and step on a bee {btw this a amber heard refrence cat instead of dog} then amber clip earaape
thats all its okay if you dont do much of i suggested
