The idea was mega interesting but I feel the execution suffers significantly. I enjoyed what you were going for but due to constant (not the fun kind) bugs it really hampered its playability. I often felt like spamming my dash was the best way forward and it worked for a good period of time. The only major (unfun) bug that really kept me from progressing was unpredictably clipping out of walls. I enjoyed "wall climbing" by clipping inside walls and manipulating the dash to not move me except the vertical dash. However being forced out of the wall for reasons I cant quite place made this potentially fun (and good buggy) mechanic very hard to pull off consistently.
I get the theme was "its not a bug, its a feature" and loved that you were trying to make genuinely buggy behavior into a fun game (thats pretty ambitious!) however playability is also important too.
I loved "glitchy" level design and background. The hint character was cute, dialog was also cute. I see lots of potential with your creativity. Thanks for uploading this, was pretty fun to play. I cant wait to see what you come up with in the future
