Man, I absolutely loved the concept that you have for this game.
The fact that it doesn't save in anyway not even locally is a big drawback.
I was nearly through with the whole game, (Had the best gun, cape, about to get the best hat)
Came back to realize I had to start over from square one? arghh
It was so close to being really cool.
To people saying it's too fast or that there are too many traps etc.
It really just takes some getting used to.
After a while and some natural frustration I got pretty good at dodging creeps, destroying crates and getting a lot of money.
It started to get really fun and then I realized once you get all the upgrades, there's not much to do,
Why label a level "world 1" if that's the Only level?
..anyway. like a lot of people have said, great potential, great concept,
just add a replay button, local saves, maybe some achievements to keep it interesting, more levels, an Option to have it free scroll or be a runner, and make the money system a little easier, I had to play for half an hour before getting to 250 coins.
great start, no doubt.
