Hello,
The reason I am rebuilding this game because I suspected level image size to be culprit of crash in android devices. In the older version all levels were made in krita while in the rebuild they are done in Unity itself with 64x64 tileset. As a result it was running smoothly in my older device(which had problem running the previous version).
I am not seeing few issues that were present in the old version. For example, sometimes if you press jump button just before you exit a crawl space, hailey dashes forward extremely fast. While climbing down, if you press space right when you contact ground, she can jump like a kangaroo. And finally scorpions where not visible for some reason (hopefully will not be present in upcoming update).
All of the sprites except the level and UI ones are reused in the newer build. There was never need of this rebuild it the older version worked in all of android devices. Well, good thing is that this game will be much better now.
