304! Clean and simple game-play loop, one upgrade I wouldn't have minded would be movement speed since getting to the tiles is so essential, and I couldn't quite get the aoe attack to work, it just seems like a smaller projectile than the LMB? I like the spritework and having to juggle going for the tiles with fighting the ghosts. Fits the theme and limitation well, nice job!

Really cool game. Straight to the point fun, I like it. The graphics, game loop, upgrades its all very satisfying, good job!

This game has pretty fun system! Although, I was at first confused at the difference between mana generation and amount, and between the LMB and RMB attacks, but I got used to it! I think one thing that would make this game a lot more fun would be different enemy types, or ways to gather solar energy! Like an enemy that drops energy, or maybe different stats.

One small thing is I think you swapped the normal and special attacks though since the description says RMB for a special AOE attack but LMB does the "big arc" projectile with half as cost as the other one. One term you could change would be "spell cost" which at a glance, I was thinking "Hmm, why would I want to increase my spell cost?" so just a slight tweak there.

The graphic style is pretty good, and cohesive. The gameplay does feel a little slow at the start due to the player's movement speed but does get hectic over time.
