First, thank you to try our game, and even more thank you for your feedback. Detailled comment by the community is really precious for us to improve.
- Busy artist and bad planning don't let us the time to have the level of graphism quality we wanted. So we can definitly improve that.
- The key, you just have to walk on them, and the same for the door when you have enough key. Number of key needed are given during the instruction, and the key color is also here to help. I agree we should be better to convey it.
- For control, I also agree. I think we could even make a pad controller and why not mouse.
- You have actually a 0.5s delay before the caracter reset to is cell, then 0.2s more after the reset before the game keep going. I don't know if 1s would be better. But more test and adjustement on that could be done.
- For the theme, yes, you don't have it from the start. It may be a problem for a jam to make a difficult level and make you need to progress to see the theme. None of us have experience on Jam, no experience in game making in general.
