Hello,
This game, within its simplicity and linearity, it was just very well executed. I understand that you did it alone in 3 weeks and you can be proud of it. It looks like a proof of concept of yours. I can see your thinking process behind it and you can consider it a sucessful game for you.
I just had a blast playing it. Would love to play more. The Benny Hill moments against the enemies are just fun. I like you clearly stating that controller is not supported. Appreciated detail. This way I avoid spending time trying it.
Congratulations!
Cheers
PS: don't hesitate to try and finish our game :)
