from the humble bundle page:
are you having problems running it on your phone?
Android apps are hit and miss on different devices; its not like Windows where it should run on all PC's given the minimum hardware specs (but on that part it is the same isn't it) due to customization by different vendors and phone services. This is also not a iOS device where its one size fits all.
If this is on the Android Market page you should look to see if anyone else is having the same issue with your product - that way the devs can be sure to look into the specific issues and work on a fix/compatibility upgrade.
Also, what OS version has the bundle been developed for? If its Ice Cream Sandwich (OS 4) then my tablet can run it by my phone can not because it won't upgrade.
