Unplayable for me, I was trying to hit z to start the game but it sent me back to the main menu. On the one time I was able to get the game to run I had no idea what the controls were so I hit esc and in the pause menu the mouse constantly moves down so I had to fight to bring the cursor up. Wish I could have played this game looks like a fun retro style bullet hell.
Update: I was able to get this game to work the trick is to not hit any key but Z or C and arrow keys otherwise it causes a crash in fact most things cause a crash in this game but that at least will bring you to being able to play which is great. For other folks reviewing hit Z once and once the player character is in the scene you should be good to play it and input keys otherwise crashes.
This game feels good when it works and gameplay wise was fun well done on the submission id look into why some the issues I had were occuring.
