You can't just do Downwell exactly the same and not even mention Downwell in your description. It's the least you can do

Howdy! I noticed randomly your game and it's really interesting! If this game will ever be released on Switch, I might consider buying. It seems like Downwell 2.0 and I can't wait to see what you can do with hats and powers during the game! Have a good day and I hope your launch will be a success, congratulations and thank you for your game!...

the game looks good but form a visual aspect it looks identical to downwell
