Cannot and will not support these types of games on this platform. I'm sure the game is fun, but this isn't the place for this. Apologies friend.

I'm reviewing this as someone who hasn't played far into the Demo but had played the original version to completion before it had a cost attached.

I'm alright with it being charged for. Its not an exceptionally great game but its alright, possibly worth the $3. As long as the updates affect the demo I don't have a problem with it being on the site. If suddenly all content was focused towards the paid versions only then I wouldn't want to see it bumped.

That said two things keep me from buying it and playing it again even though I've got a mild craving. First is the lack of a web version. I don't want to have to download an app or play through steam to play the game. If there was a way to play it as a web version I'd be more interested.

Secondly, and this is more a deal breaker when it comes to returning to the game. The offline rate is abysmal. 1 hour offline equals 2 hours of in game time. And since normally its 1 second per hour that means you get a rate of 1:1800. For every half hour offline you get 1 second of progress. Why even include it at that point? Maybe this was to make game overing due to offline negatives a lesser issue but I really would rather see some kind of rate like 1:4 or even 1:1. Don't punish the player for not keeping the window open. There's not really a reason to in a single player game.

The game is kinda fun and goofy but the whole demo thing completely destroys the game's charm. I didn't think that it's allowed to post pay-to-play games here and wasn't expecting to find one. And even if you would like to support the dev and not make them, quote, "work for free" (funny you mention this on a website with FREE games) - you'd have to play elsewhere because it has no full web-version. Bruh.

this game is only a demo and requires you to pay 3 dollars for the full game, so be warned

developer response: Updated listing to more clearly state that it is a demo

Never create Pay To Play games and release them. - Stevens good side.

developer response: Note to self: in the future do work for free.

one thing needs to be made clear, the low ratings aren't because people 'hate supporting developers' or dislike the game. although nothing groundbreaking it is pretty fun.
it's just that people go to online game websites such as kongregate and galaxy expecting to be able to play a game for free.
websites like this are for people to just click on a game that looks interesting and play it, no strings attached. this just isn't the correct platform.
if you're going for a paid approach, you're better off on websites such as where people actually see the price tag beforehand and expect to pay for the games that they play.
the low ratings aren't a product of the game itself being bad, more a product of horrendous marketing, for a lack of better word.

I played this when before it became a demo and it is a shame that I cannot complete it now :(
