hey, thanks for making me aware of this issue. i just uploaded 1.1.3 which should hopefully have a lot of optimizations.
what kind of device are you using? is the performance improved?
This new is much better, quite playable. There is still some slowdown at the beginning of a level (how much depends on how many enemies there are) that eases off as the level becomes more empty, but it’s much less than before. So, thanks!
ps: I’m using Android 11 running on a Nexus 7 (2013). Old, I know, but still very capable and a great book reading tablet.
