Hello!
None of them require coins, but Pede Off and Dropsum Colours have the coins functionality in them.

With Pede Off you can purchase power-ups to make your game easier for you (or you can earn experience by playing a lot and get them that way).

Dropsum Colours is more a donation thing.

Thanks

Nick

Thanks for the comments :)
I'm working on a platform game at the moment. so, you know, in about 4 months time it might be done :)

Hi Nick, I agree with puretaine, dropsum was cool and dropsum-colours is super cool.
I like all the cool features and the gameplan. It is truely a well made game.
And what a great response to "kongregate user", well done.

Take care

so you enjoy making games, cool - i work in a hotel but they cut my hours so now i even more time to play ur games lmao.

Bye bye

Hi. I'm fine thanks very much. Busy at work doing my proper job (guess what - I make videogames for a living as well as doing Flash stuff in my spare time!) and relaxing (mostly) after finishing off Colours.
Cheerio

Hi Nick

I love all your games, how are you?

;_; how could YOU!!! (dropSUM)

I LOVE ur Games Plz Add me

you don't actually. If you don't like the game you can go away and leave me in peace. If you do like the game but don't want to pay then you can earn all the unlockables by playing the game more. As you managed to get a score of 111 I can only assume you are either terrible at the game or (more likely) you didn't want to bother playing it. So I wish you all the best and good luck with life.
