Thanks for the feedback, appreciate it!
Yeah we don't really understand the random (or maybe not so random) crashes, as we all had different experiences. For me the crash consistently happened after the third level, while for others they could play the whole game without issues.
You're right about the cumbersome..ness? the plan was indeed to make something that requires you to make choices on what you are focusing on. We barely even made levels to explain all the skills!
Once again, thanks for playing and for your feedback!
