Level 3 only has 4 coins, but you need to collect 5 for a perfect score. Perhaps a coin locater tool could fix this since it would clarify for both the developer and player how many coins there are, and where?
Needs a suicide key to overcome glitching yourself off the screen. Since it has neither that nor a save feature, I have to restart every time it glitches. 1/5.
I agree with some previous commenters; level 23 is ridiculously difficult, easily the hardest single level (i.e. not counting competitions) in the game.
Why does the video walkthrough have you doing the impossible on level 11? I follow the same steps as the video, but the platform never rises quickly enough.
Why are the enemies in the first level immune to damage? With a maxed flare (45 of the initial 50 spent, all that is possible initially), I can't kill 1 creature, even with spamming just the 1.
