Helios, the new owner of the GameCore engine, and Gekido have responded to the user outcry over the Indie tool limitations and have just released an update:

"1) We have removed the file size & object limits for the Indie release.

2) We have added the post-processing / hdr functionality to the Indie version

3) We increased the size limit for the casual version to 100 Mb, and removed the object count limit.

4) Added Object Grouping back into the indie editor."
