I found Lazerynth to be enjoyable. As for bugs, the soundtrack seems to be on a flat playthrough rate and at a certain point I think I hit the end of the loop of them until the boss rolled in. Then when said Observer rolled in I was a bit amiss as to what to do since the red squares he was dropping weren't doing any damage. Took my a bit to realize that I was supposed to walk up and bop him, and when I finished it didn't seem to result in any kind of end screen.

All in all I'd say this was a lot of fun and would like to see more variety in color schemes and arrangements for the levels. Feel like some neon sickly greens could go good with the whole vibe.

As for polishing up the boss fight I think it might be fun to chase it through one of the Lazerynths proper, having to dodge active lazers while punching the boss in the eye could be a lot of fun. Of course this could also serve as another boss battle.

you deserve a lot of attention on this its fantastic! i love the music and the art and the controls feel just right for this style of game, the only bug i encountered was that the music seemed a lil loud and i couldnt navigate to audio settings in the settings menu. but thats so very minor i dont want it to detract from the impression this left on me, i hope this brings you fame and good fortune sir, great job!
