Hi, thanks a lot for playing my game!
1. I think you locked yourself out at the 2nd gate with the gear mechanism. But if that's not the gate that locked you out then please give descriptions to let me know.
2. Movement isn't glitching but the problem is with camera I think so because it never glitched for me, when I tested it before release. Though I know it still has some bugs like the end screen etc. Also I just played the game but couldn't find a glitch so please let me know where the game glitched for you so that I can fix it.
3. Shooting at one direction was designed because firstly this is my first finished game so to speak and I hurried myself to finish it as best I could before submission time ended. If I had more time I might have made it shootable in for all the four cardinal directions but designing everything from sprites, levels and game mechanic is very tiresome when doing it by myself.
So I hope you give this game a decent rating that I may not sink under the sea!
Thanks again and have a nice day!
