Thanks for your feedback! Did the image with the controls on the titlescreen helped?
With more time I would have added a short on screen tutorial for the first wave.
For me it was telling what character was I controlling. Since the playable character was already moving in some directions couldn’t tell if input was being received at first. Probably because I didn’t read the description clearly.
Oh yes you’re right! At first I wanted to start the very first wave by the player choosing the initial direction.. but I forgot!
