Hmm.... Yeah... I like it! Challenging and addictive. No problems with the difficulty, because this is really a high score game. What people might not be realizing is that this is Flappy-style game hidden beneath a MUCH more engaging, creative concept. Good on you for actually coming up with a new approach. In all the Flappy clones I see --and I hate Flappy Bird-- only one in every fifteen actually try something new with the concept. The game requires several different skills. Hand-eye coordination, careful judgement, patience, and quick multitasking. The fact that everything is randomized maximizes replay.
I like the motif here. We have an elemental mage who uses wind, fire, lightning, and maybe some telekinesis to bust through all these levels. Beautiful title screen, but the lower-grade graphics on the game itself aren't a problem because this is a survival game. Any more distractions than we
already have would be unwelcome. The music, on the other hand, is good. Upbeat and energetic to keep the player motivated.
I can see how you could expand on this. New obstacles and monsters, more spells, power-ups, changing backgrounds, increasing difficulty. One thing you might want to do is add a "Casual" mode, where the player gets three hits before failing. This would help people practice before tackling the real challenge, and you could have two different leader boards. The medals already increase replay.
Honestly, it's a pretty cool attempt. Keep growing.
