Casimir Thank you for testing and leaving feedback.
1. The game in the current state has a button remap system so you will be able to setup the controls to your desired layout.
2. Yes, I do everything on the game including the art so glad you like it
3. Good, the current version is even more optimized than the uploaded one here so should run on most systems without a problem.
Maybe I'll upload the new bigger version here, working on a demo atm
