I bought Dungeon Hunter because a friend of mine has it on his iPad and it looked pretty sweet. It runs great once it loads, but load times are a bit long.
I did not turn off Sense to play and it's pretty smooth.
After installing it and running it for the first time, it comes up with a message that it needs to download another 125MB of stuff for the game (don't worry, it saved it all to the SD card).
My only complaint is their DRM policy. I bought it through their website since it's not in the Android Market, and apparently it can only be installed once on one device...ever. In other words, if you wipe your phone for any reason and try to reinstall the .apk, it won't let you and you have to buy it again. That is seriously lame on their part. If I knew that going in, I would have thought twice before supporting them.
But on a gaming front, it's awesome
