Pretty good submission! I do think getting from Alchemy to golf is a bit too much of a stretch :P.
Some points of feedback:
- The controls are somewhat easy to find out by trial and error, but it would be better if the player gets some aid.
- De levels with the rotating sentry and tanks don't properly reset. Projectiles stay live causing you to die twice in a row in some situations, that is quite annoying.
- I would personally prefer if the power meter starts at 0 every time you come to a stop
