Hey thanks for playing my game and providing some feedback. I'm glad you had fun, and enjoyed some of the effects.
Interesting comment regarding the overheating effect. I dialled this back from how it was in earlier builds as it felt too much, and at one point I considered taking it out of the game completely, but I really like the mechanic of it to make players use their bullets more wisely and not just mindlessly shoot continuously. At that point however I think enemies were faster and stronger, so I might be able to get away with dialling back up a notch. Thanks for the feedback :-)
