Everything about the presentation is clean, simple and readable to a fault really. This felt very derpy in the best way possible.
The mechanics here are very well thought out and fun, though I feel that the actual implementation of the theme is somewhat loose.
The boss design might have been a little too simple and repetetive in some cases imo. As an example, I think a little more could have been done with the weakpoint moving around more and making the fights more dynamic.
Because as a whole, they were all a little too simple to beat imo. Although maybe it's for the best that most of the boss designs were simple since they were instantly understandable lol.
This is more of personal issue than anything else, but I think the first room with spikes was definitely somewhat of a difficulty spike ( pun not intended ) because I never really realised until then that the rocket changes your direction lol. Mostly because I never really had to use it at all for any room before
( Apart from starting the room of course. Tbh, you can ignore this because I think anyone who isn't pig-brained like me will probably get it quickly lol )
As a whole, this is indeed a pretty cool entry lol. Great job on this
