This is a pretty good reproduction of CrimsonLand by 10Tons Games in Flash. You got their permission to use their game, right? I'm surprised 10Tons Games wouldn't want to be credited in some way in a clone of their game, CrimsonLand by 10Tons Games.
I love CrimsonLand by 10Tons Games, so this was fun to play for a while. You forgot some of the CrimsonLand by 10Tons Games perks ('upgrades' in your clone thereof), though, including some of my favorites, like telekinesis. That takes some of the punch out of the bonus magnet + bonus economist + telekinesis trifecta. I also missed my homing rocket shotgun + angry reloader + fast reloader combo. Further, the descriptions in this clone lack the charm of those found in CrimsonLand by 10Tons Games.
CrimsonLand by 10Tons Games was, is, and ever shall be a great game whose elegance and effectiveness cause it to be recreated quite frequently in Flash. If you love CrimsonLand by 10Tons Games as much as I do (something tells me you do), you should probably credit it when credit is due (which it is). Otherwise, you really need to add something new to the mix, rather than just cutting good features. I saw a CrimsonLand by 10Tons Games clone once that had a robot instead of a soldier, had some non-ripped-off weapons & bosses, etc., for example. That was cool.
